How to find out the size of the chains for the chainsaw: the markings table
Chainsaws are widely used in industry for SPIL, as well as processing the trees fallen during the harvesting of forests, and in the private farm to care for the garden, construction or harvesting of firewood. In our country, professional saws produced by Husqvarna, Oregon, STIHL, Partner are most common in our country. The chain is an important working detail of the chainsaw, on the quality of which the performance of the saw depends. This article will tell you about the main characteristics of this saw set. From it, readers will also learn how to determine the desired size of the chain for the chainsaw.
Daws with a gasoline engine are used for longitudinal and transverse sawing of trees trunks, as well as finished lumber. However, in order to correctly install a chain of the required size on a motorope, you need to find out its design, which was invented in 1947 by Joseph Cox and since then has not changed significantly. At the enterprises, the worker should find out the safety rules when sawing lumber with a professional tool. After passing the introductory briefing, admission to work is put. The correct selection of the chain increases the performance of the chainsaw. The saw chain consists of three types of links:
All links are made of highly alloyed steel and are connected by rivets. In good quality chains, cutting elements are made of winning or other alloys of increased hardness. They can saw different rocks of wood, concrete, thin metal and other materials. Incisors are right.Handed and left.Handed and located and stand on the chain in turn. They have a cutting edge and a limiter that regulates the depth of the cut.
The purpose of the leading links, which are called shanks, is the transfer of rotational movement from the saw engine to the chain through the leading stars. This ensures its stable position on the removable bus. For reliable fastening of incisions and shanks, the design provides for connecting links.
How to measure the length of the tire on the chainsaw
Many novice gardeners make mistakes when choosing a saw part for their tools. In this case, a table of selection of chains for chainsaws can help. It was created taking into account the most popular models, which makes it possible to accurately choose a saw set of almost every gardener.
Advantages of the table for chainsaws
A table for chains of chainsaws is the best way to visually choose a headset. With its help, any novice gardener or roller does not need to seek a product for hours, the characteristics of which would correspond to the size of the factory kit.
When creating it, the following factors were taken into account:
- The length of the tire indicated in centimeters. As a rule, it is calculated within 30–45 cm. Sometimes there are exceptions when you need to find an element for high.Power saws;
- A chain step is a parameter that is equal to the distance between the three rivets located nearby;
- The total number of links is one of the most important characteristics. It depends on it whether a new part will stand on the standard saw of the saw;
- The thickness of the shank indicated in millimeters. This parameter is measured
Seedgenzirkul. In most cases, it is in the range from 1.1 to 2 mm.
Thanks to the totality and accessible presentation of these data, everyone will be able to understand the specified information.
Rules for use
The left column contains a list of the most popular chain saw models. All other columns indicate the dimensions of the tires and other working parameters of the saw headset. Thanks to such a data layout, any beginner foul can find an element that is suitable for its tool in a few minutes.
The tire provides the chain of the chain of the chain, and also moves the chain using the installed stars.
Standard tire size sizes:
- Length: 300 (mm), 350 (mm), 450 (mm), 530 (mm), 630 (mm), 750 (mm), 900 (mm), 1050 (mm).
- The thickness of the leading link: 1.1 (mm), 1.3 (mm), 1.5 (mm), 1.6 (mm), 2 (mm).
- Chain step: 6.35 (mm), 8.25 (mm), 9.52 (mm), 10.26 (mm).
- Number of links: 52, 56, 64, 68, 72.
Methods of marking tires for chainsaws:
The main symbols of tire marking for chainsaws are the numbers indicating the length of the tire (cm), the chain step (1/4, 3/4, 3/8, 0.325, 0.404), and the number of links.
For example, the tire is 40×3/8×56, where 40 is the length of the tire (400 (mm)), 3/8. The chain step (9.52 (mm)) and 56. The number of teeth.
The third main parameter when selecting the chain: the length of the chain (number of drive links).
The length of the chain is determined by the calculation of the number of drive (internal) links of the chain. Important:
- The cutting links do not determine the length of the chain (do not count them).
- The length of the guide tire does not determine the exact length of the chain (for example, on a saw with a tire of 16 “(40 cm), a chain of 55, or 56, or 57 links, depends on the mechanism of the chain of a particular saw model).
- A circuit of about 55-57 links is not suitable for you, only a certain size recommended by the manufacturer of the saw is suitable.
The size of the chain
This parameter always depends on the size of the tire installed on the unit. If you accidentally purchased a smaller chain than your tire, it will not work to wear it. If this element has a size exceeding the size of the tire, you cannot pull it. Both options do not allow the use of inappropriate chain sizes. They are usually indicated in inches and have the following values: 10 ″, 12 ″, 13 ″, 14 ″, 15 ″, 16 ″, 18 ″ and above.
The length of the chain is determined by the number of links. The links mean connecting links that enter the groove tires, and not cutting teeth. When buying, you can indicate the seller either the length of the part in the inchs, or the number of links that make it up. Some manufacturers instead of length indicate the number of links in the saw element. As a rule, this number does not depend on the thickness of the tail, step and height of the profile. For example, a low.Profile chain with a 1.3 mm leader thickness can consist of both 72 links and 56 links or their other number.
Characteristics of chainsaws
The power of the chainsaw determines its performance: the greater the power, the faster it will cope with the trunk of the same thickness. But this does not mean that powerful saws are definitely better than low.Power. Powerful saws are heavier and much more expensive. In many cases, a light low.Power saw will cope with the task better.
For long.Term work on a roll of forest and sawing logs from 40 cm, you will need a saw with a capacity of 2500 watts (from 3.4 l/s) and tire from 45 cm. Such an instrument belongs to the category of professional, weighs from 6 kg and costs respectively.
If the chainsaw is supposed to be used during the construction or harvesting of firewood for your home or bath, then the optimal choice will be a mid.Power chainsaw: from 1,500 to 2500 watts (2.04. 3.4 l/s).
Daws with a capacity of less than 1,500 watts are suitable for cutting branches and sawing small parts. But lightness and compactness will allow the use of such saws in constrained conditions.
The maximum depth of cut depends on the length of the tire. The larger the length of the tire, the greater the thickness of the log or the beam can be cut. But the greater the length of the tire, the more power is required to overcome the increased friction of the chain. Buying the saw of a well.Known manufacturer, you can be sure that its power corresponds to the length of the tire, but among cheap saws sometimes there are copies with low power and a very long tire.
If there are doubts in accordance with the length of the tire and power, then you should FOCUS on the fact that the optimal power for the tire is 40-45 cm-2 kW, 35-40 cm-1800 watts. Saws with lower power are usually equipped with 30 cm tire.
The chain pitch is called half the distance between any three rivets. The size of its teeth depends on the chain pitch.
The chain step should also correspond to the engine power: large teeth sawed faster, but such a chain will require greater power. In addition, the larger the chain step, the rougher the cutter and stronger vibration. When clicking on the saw with such a chain, it will be more difficult to hold in the hands.
A step of 0.325 ″ (8.25 mm) provides maximum purity of cutting for chainsaws. This does not matter for the rolling of trees and the harvesting of firewood, but for builders this factor may turn out to be important.
Step 3/8 ″ (0.354 ″ or 9.3 mm) provides acceptable productivity and is used in most household chainsaws.
Step 0.375 ″ (9.5 mm) is used on powerful chainsaws, from which maximum performance is required. But working with such chains is more difficult and dangerous.
The larger the width of the tire groove, the thicker the guide elements of the saw chain, the stronger and less susceptible to wear.
Tires with a bandage width of 1.3 mm provide the minimum chain weight and are used in low.Power household chainsaws.
The tires with a 1.5 mm guide width provide greater wear resistance and durability of the chain and are used in a semi.Professional tool.
With a large depth of cut and prolonged work, the load on the chain grows many times. In this case, strong chains with wide guides and the corresponding tires with a groove width of 1.8 mm are used.
The performance of the saw depends on the maximum speed of the circuit, but only if the engine power allows maintaining high speed under load
If high performance is required from the saw, first of all, you should pay attention to power, and only then. To speed, tire parameters, etc
The mechanism of tension of the chain allows you to prevent sagging the chain due to its stretching. Distinguish of instrumental and nonsense mechanisms. The instrumental mechanism requires a separate tool for tensioning the chain (usually screwdrivers). In addition, on some models with instrumental tension of the chain, before the tension, you need to remove the cover of the leading star, which may also require time and the presence of the appropriate tool. The misnstop mechanism is much more convenient, the chain is pulled with its help simply by turning the tension regulator on the saw housing.
Equipment. Chainsaws require periodic maintenance using a special tool.
If the kit does not have the corresponding set of tools, keys and screwdrivers, then they will have to be purchased separately. Especially if the tool is used in the saw instrumental mechanism for tensioning the chain.
It will also not be superfluous in the kit of the candle key. At first, to remove the “flooded” candle for drying repeatedly.
Making Chain Saw to steel cutting
The presence of a measuring container for fuel will help to observe the necessary proportions when preparing the fuel mixture. Two.Stroke chainsaw engines require gasoline as fuel mixed with special oil.

Tire for a chainsaw is one of the most important parts of the tool
If a few decades ago, a chainsaw for many was considered unrealistic luxury, today it has become an indispensable assistant in the household. Indeed, now such a saw is an integral attribute in the household, in a private house, in the country or for those who are engaged in a sawing or roll of trees, as well as construction work.
Fortunately, the for unprofessional and professional chainsaws are quite acceptable today, which allows you to purchase them almost everyone. However, one should not forget that any equipment during operation needs prevention, and sometimes also to replace the nodes and spare parts.
There are frequent cases when a tire for a chainsaw requires a replacement, which is quite simple, for example, in the Helphouse Internet Market Mark. However, many are afraid that they do not know how to choose a tire for a chainsaw, because their size is so diverse that it is easy to get confused.
How to choose a tire for a chainsaw
If it is incorrectly selected for the chainsaw tire, not only worsen the technical characteristics and productivity of the tool, but it will simply be dangerous to perform work using it. After all, if the chain does not perfectly “sit” on the tire, then at any time it can simply jump off it and cause a serious injury. Therefore, you must know how to measure the length of the chainsaw tire, because this parameter is one of the main ones when choosing.
Useful tips on how to measure the length of the chainsaw tire:
- It is necessary to measure the distance from the end of the chain saw to the place in which the tire enters the case and round the resulting value to the nearest even number.
- Calculate the total number of drive links in the chain.
- Make measurements to determine the height of the chain.
If you cannot figure out how to measure the length of the tire of the chainsaw, it is better to seek advice to professionals.
The thickness of the tail
The thickness of the elements depends on this characteristic, as well as the width of the leading link. There is a direct connection between it and the size of the groove of the tool intended to stretch the chain. When choosing a saw chain, it should be taken into account that it can fit in the groove.

The thickness of the tail affects the strength and qualitative properties of the chain, its reliability and endurance. Standard values of 1.1, 1.3, 1.5, 1.6, 2 mm are considered standard. The narrowest chain is used in compact houses of domestic class.

Features of the design of chains of a professional level
In the geometric form of cutting teeth, the type of profile is distinguished for the most commonly used:
- Chipper, or sickle. Provides large cut speeds. It is easier to sharpen it, while it is not required to very strictly observe the angles. The profile has the ability to self.Cleaning from sawdust and copes with the sawing of contaminated and wet materials perfectly. The increased area of contact of the tooth with the material additionally loads the engine. For sawing such a profile, it is good to have a power supply reserve. The disadvantage is the occurrence of overloads when sawing solid wood or knots.
- Chisella, or “Seven”. The cutting edge is straight, in the profile it is similar to a stylized number 7. The cut is more precise, but it is more difficult to tighten them, it is necessary to withstand the corners with high accuracy. In case of violation of the sharpening angles of several one or links, all the advantages of the profile exactly instantly go to naught. It is better to drag such chains on automatic machines that provide high stability of parameters.
Chiselic profiles are used both in household and professional chainsaw models.
Why is a table that determines the size of the chains
The reasons that reduce the productivity of saws with the internal mountain engine are the wrong selection of size, profile height and chain step. When buying it, you need to carefully study the marking applied to the closing links, as well as the working characteristics indicated on the packaging. If it is impossible to decipher the marking and there is no package to the product, the best way is to choose the product according to the dimensional table. They can be found on the official sites of well.Known manufacturers, such as Ukvarna, Shtil, Oregon. Consider such tables that will help you choose a chain of the desired size for your chainsaw. In the left column are the most common motopyl models in our country. In the following columns. The main parameters of saw nodes. Having found the right model, you will quickly find out which chain is suitable for your tool. The chains produced by other companies may be suitable for chainsaws released by one company.

Tire of the chainsaw: how to measure, choose, install and fix
Control of the movement of the circuit with fixing its tension and regular lubrication is provided by one simple and absolutely indispensable element. The saw tire belongs to the category of consumables, since it takes on peak loads that deform and seriously wear it out as it is working. This article will briefly and clearly show what criteria to select a new part, how to install on the tool and make easy repairs.
The general idea of the structure of any element consists of knowledge of its components and an understanding of their interaction. To operate the tire as long and efficiently, it is useful to have a clear picture of the principle of its action. The functional role of the detail in the chainsaw system is extremely clear to everyone who observed this tool in work. First of all, the tire serves as a guide for the chain, as well as a means of its tension and lubrication.
With a cursory examination of the element, it seems that it is cut out of a solid sheet of metal. In fact, the tire consists of 3 plates (2 side and one central), reliably fastened with rivets. The central element is an order of magnitude shorter and thinner than the lateral, due to the formation of guide grooves in which the shanks of the chain are immersed. The free space in the front (on the nose) of the tire is occupied by a led by a stars, which ensures the free stroke of the chain during tension.
To facilitate movement and protection against erasure, the asterisk is installed on the bearing, the central part of which is attached to the side plates. For the maintenance of a mechanism expressed in cleaning and lubrication of rollers, special holes are provided on both sides of the tire.
In the tail of the guide, there are a number of technological holes. The largest, elongated opening, provides an even installation of the canvas along two studs fixed on the engine crankcase. In one of the 2x symmetrically located holes, the finger tensioner is inserted, and the oil pump fitter includes the smallest that supplies the lubricant on the shank of the chain when working.
How to use a table?
The left column indicates the most common models of chainsaws, in the subsequent. Leading criteria. Having found the desired modification of the tool, you can find out the necessary data regarding its saw part for several seconds and quickly resolve any controversial situation.
The chain of the chainsaw performs an important function when working. It is on it that the performance and speed of the cut.
Correctly selecting a saw set for a chainsaw with low power, you can significantly increase the characteristics of its work. In this article, we consider the types of chains and their main parameters.
The step of the chain of the chain. Table
Taking into account the size of the step, at the moment the chains are not divided by several subtypes:
Chain Saw to concrete groove cutter
|No||The distance between the rivets||Chain step (width in inches)|
Chainsaw \ Saw Chain Code Chart
As can be seen from the table, the chain step is designated as a conventional number (3/4) and decimal. “0.375”. Such a division is caused by the similarity of decimal values - “0.325” and “0.375”, since the difference in one digit created confusion when selecting a saw. Therefore, at one time, a decision was made to establish two different designations: decimal and ordinary fractions.
The step is stamped in the area of the special restraint of the cut depth on each tooth.
The pluses of chains with a big step include:
But it should be noted that a wide saw requires the use of a more powerful engine, which in turn significantly increases the resistance.
The advantages of chains with a small step are:
Advantages are achieved due to a large number of teeth and a small distance between them.
The whole well.Known classification of chains is based on the features of their marking depending on the step, which is designed for certain needs and is made for a specific power of electrical equipment. For a better understanding of each type of step, they should be considered separately.
Sharpening of saw chains
The productivity of pure sawing and the convenience of working with it, the value of the required effort and cutting effort, its durability depends on the high.Quality sharpening of the saw chain. The earlier the cutting teeth are sharpened, the less it will be necessary to remove the material during the next sharpening, which will ensure a longer service life of the circuit, so the main rules of sharpening are the principle: often sharpen. It is not enough to remove.
The most visual sign of the need to sharpen the saw chain is to increase the resistance of its supply, as well as a decrease in the size of sawdust.
When working with a blunt saw, fuel consumption increases, the wear of the saw apparatus and the saw engine increases. All saw chains can be sharpened both using special files and holders, and on special machines, except for Duro circuits, which can only be sharpened on special sharpening machines equipped with grinding circles with diamond spraying.
When sharpening a saw chain former, it is necessary using a measuring tool, such as a caliper (rice. 4.26), install the shortest cutting tooth in the chain, mark it, since in the future it will serve as a standard for the length of the remaining cutting teeth.
After sharpening, all cutting teeth should have the same length. Otherwise, the cutting teeth will have a unequal height, which will lead to a restless operation of the chain and can cause its gap.
Chains with different steps are pulled by files of different diameters. It is required that the file for 1/4 diameter protrudes above the top of the tooth (rice. 4.27).
The use of a special holder, as well as a file selected to the corresponding circuit, guarantees the correct fit of the file to the tooth during sharpening: while the angles of the front and horizontal blades are automatically obtained.
A set for sharpening saw chains in the field consists of a holder with a round file, a flat file and a chopping template.
There are special marks that increase the convenience of sharpening (rice. 4.29).
The file of the file should be carried out in such a way that the angular risks indicating the angles of sharpening 30 ° and 10 ° are parallel to the saw bus (rice. 4.Thirty). An example of the correct position of the holding when sharpening the angle of 30 ° is also shown in the rice. 4.Thirty.
The holder with a file should be held horizontally, withstanding the perpendicular to the lateral surfaces of the links and the saw bus (rice. 4.31).
For each tooth, two or three sharpeners are usually enough. The number of sharpeners and the effort of pressing on the file should be the same for all teeth, otherwise there is a risk of teeth of different lengths and, accordingly, heights.
Current movements should be continuous for obtaining an acute and smooth edge of the cutting edge. It should be sharpened only from the inside, by moving from yourself, when moving back, the file should be raised. During operation, the file must be periodically rotated to avoid its unilateral wear.
Thus, the first row of teeth is first sharpened, and then the second. The leading and connecting teeth should not be sharpened.
Since when sharpening the chain in the field, using a file and holding, to obtain the same angles of sharpening and length of cutting teeth, without deviations, it usually does not work, then after each fifth sharpening, depending on the degree of error of previous sharpening, the chain should be given to a specialized Workshop to give the right size on a special assault machine.
После каждой заточки должна проверяться высота ограничителя глубины. Для этого используется опиловочный шаблон, с его помощью можно проверить все важные углы и расстояния пильной цепи.
Соответствующий пильной цепи опиловочный шаблон накладывают на цепь (рис. 4.32), наивысшая точка ограничителя подачи должна находиться на одном уровне с шаблоном. Если ограничитель подачи выступает над шаблоном, то его обрабатывают плоским или трехгранным напильником.
При работе с мягкой древесиной в теплый период года величину подачи на зуб можно увеличить на 0,2 мм от рекомендуемой. Для этого после снятия шаблона надо сделать еще два точильных движения напильником или использовать шаблон с большей величиной подачи на зуб, например 0,8 мм вместо 0,65.
После коррекции высоты ограничителя подачи, следует дополнительно подточить его наклонную плоскость согласно сервисной маркировке (рис. 4.33). At the same time, you need to ensure not to reduce the height of the feed limiter.
At the saw chains equipped with tubercular leading links (with the number 3 in the brand), the upper part of the connecting link (with service marking) is processed simultaneously with the feed limiter, the rest of the leading link should not be processed, otherwise the tendency to reverse return will increase. In addition to a sharpening set, to sharpen the circuits, you can use sharpening devices and machine tools.
STIHL sharpening machines include HOS and USG machines, which are structurally similar to domestic sharpening machines LV-9 and LV-116.
HOS sharpening machine has an unregulated slope of a grinding circle, already adapted to cutting teeth, this machine is not suitable for sharpening the STIHL DURO chains.
Unlike HOS, the UGS sharpening machine has the ability to adjust the inclination of the sharpening circle, can be used for any saw circuits, including STIHL DURO, as well as, with additional devices, for sharpening knives and saw paintings.
To reduce errors during sharpening, you should periodically selectively check the correctness of the front angle and angle of sharpening. To do this, use the appropriate circuit of the sawing template (rice. 4.35). Windows for sharpening angles 10 °, 30 ° and 35 ° are knocked out on it. To control the front angle on the side surfaces, Windows are knocked out or angles 60 °, 75 °, 80 ° and 90 ° are marked at the edges.
To check, the sawing template is laid on the saw chain so that the lateral surface completely adjacent to the saw chain. Then you need to remove the template along the circuit until the checking cutting edge rises to the upper edge of the corresponding window (front angle or angle of sharpening). The angle is considered correct if the edge of the window and the cutting edge are parallel.
When sharpening the chain, special attention should be paid to the correctness of the selection of a sharpening set and adjustments of the sharpening device or machine. The correct values of the front angle and angle of sharpening are achieved only with the correct selection of the tool. Holding a file and a file, a specialized sharpening circle. Each deviation will affect the correctness of at least one value. For example, if too thin a file is used or the file of the file sets the file too deep, then it turns out too small (too sharp) the angle of the front and horizontal blade. On the contrary, when using a large diameter file or with its too high rise, the power of the front and horizontal blade turns out to be too large (too dumb).
Cutting depth. A parameter depending on the tooth profile
The larger the tooth profile (size), the more the depth drank in one pass. The higher the cutting depth value, the greater the value of the tool performance. It is important that the higher the depth of cutting chains for chainsaws, the greater the load on the engine engine.
The height of the links also affects the strength of the teeth, and the greater they are, the lower the strength indicator. Standard models of the saw headset are available in two versions of the height of the teeth. 0.635 and 0.762 mm. Products with a lower parameter of the profile height are called low.Profile, and with large. Highly profile. The depth of sawing affects the cutting time of wood.

Drive roller chains Designed for power mechanical gears of various machines and mechanisms. Of all the drive chains, the most widespread. There are three main standards regulating the parameters of drive roller chains-GOST 13568-97, adopted in Russia; ISO/R 606, British standard adopted in European countries, and ANSI B29.1m adopted in the USA. The chains of this type can be made collapsible, with a direct and curved contour of the plates, as well as with various types of anti.Corrosion coatings. The sizes of roller chains have complete analogues among the chains of American and British standards.

If the saw saws crookedly. Reasons and what to do
Often, sawmiths are faced with the fact that at one moment the saw begins to saw crooked. This causes not only inconvenience, but also complicates the treatment procedure. The sawmill has to make efforts not only to keep the tool, but also to equalize it. Few people know that it is prohibited to operate a tool with such deformation. We will find out what is the cause of the uneven sawing of the chainsaw, and what is dangerous for the sawmill.
If the saw begins to cut crookedly, then this indicates the presence of an inconspicuous deformation of the tire. The deformation is associated with the side of the tire, which has uneven wear. As a result, the chain is located not evenly, but with a slight skew. The skewing value can be invisible to the eye.
It is interesting! The cause of the uneven sawing of a chainsaw may be uneven wear of the link links or their incorrect sharpening. Before replacing the tire, make sure that the chain is working.
Eliminate the malfunction in the form of uneven wear of the tire can be replaced. It is almost impossible to carry out uniformly grinding sides of the guide, so it is recommended to replace it with the chain. The danger of the exploitation of a deformed guide chainsaw is that the tail of the chain can jump out of the groove, which will entail not the most prosperous consequences.
The tire of the chainsaw, like the chain, experiences heavy loads, so its wear is observed. With wear, it is important to replace the part in a timely manner without waiting for adverse consequences. How to choose, and what to consider when buying a tire on a chainsaw, is described in detail in the material.
