Chains for chainsaws
The chain is an essential part of any petrol or electric chainsaw. The efficiency of the tool, as well as the amount of fuel he consumes, depends on the serviceability and condition of this part. It is often difficult for a beginner to know which chainsaw chain is better. In this case, you need to learn the basic characteristics of the saw headset, as well as the rules for its installation and maintenance.
Today the market is overflowing with many kinds of sawing elements. They are divided by their characteristics and fall into several categories.
According to the type of sawing direction, we distinguish between such types of parts:
- transverse. the saw headset of this type is characterized by the effect of smoothing vibration and reducing the load on the engine of the tool. This makes it easier and more convenient to use the saw;
- longitudinal. parts of this type are distinguished by high performance.
Another important characteristic is the chainsaw chain pitch.
According to this factor, the saw chain is divided into these types:
- 0.25 or 1/4″. these parts are used to equip one-handed household saws;
- 0.325 or 3/8″. elements with this pitch are mostly used with semi-professional tools;
- 0.404″ or 3/4″. these are suitable for use on concrete or aerated concrete.
As a rule, the performance of the set depends on the pitch.
Third feature. shank thickness. In order to install the element, it is necessary that this parameter coincides with the dimensions of grooves in the bar of the tool. The bar nose thus remains firmly fixed to the guide bar and the risk of it accidentally slipping off is minimized.
The following types of parts are on sale:
- chains with a shank thickness of 1.1 mm. these parts are used to work with household tools;
- elements with shank thickness of 1,3 mm. this type ofset is used to equip semi-professional chainsaws;
- products with shank thickness of 1.5 mm are used for regular equipment of small but powerful household tools;
- parts with shank thickness of 1.6 to 2 mm. this is a headset to be mounted only on powerful industrial saws.
Many experts also divide the tools by the possibility of their installation on chainsaws with self-sharpening function. On this basis, self-sharpening chains or chains that need to be sharpened manually can also be found on the market.

Choosing the right saw headset for a low-powered chainsaw can significantly increase its performance. In this article, let’s look at the types of chains and their basic parameters.
Choosing a tire for a chainsaw (electric saw)
One of the parameters of a tire is its size. As a rule, the tire size is given in inches, sometimes in centimeters. We recommend that you use an inch size. The most commonly used tire sizes are 11″, 12″, 13″, 14″, 15″, 16″, 18″, 20″, 21″, 22″.
A smaller guide bar is used for easier work. For example, a chainsaw with an 11-13″ bar installed is used as a lopper, and is also used for cutting small, non-thick boards. This bar is small and allows you to run the chain at high speed, so you can work fast. The most used and universal tire size is 14-16 inches. This guide bar also makes it possible to cut firewood and use a chain saw as a pruner. 18. 22″ tires are used for cutting thick trees when cutting firewood. These bars are used in semi-professional, professional and high-powered saws.
The size of the guide bar you can use should be listed in your saw’s instruction manual. It is not recommended to install a longer tire than the manufacturer specifies, because it affects the engine speed. The longer the bar, the more effort the engine puts into turning the crankshaft to accelerate the chain, and this affects engine wear. This is the most important rule to follow.
Amateur saws use narrow and flat (low-profile) bars. These tires do not kick back and are very safe, which novice users will appreciate. There are also lightweight bars for chain saws. These tires have reduced weight, which allows you to work and operate the chainsaw in a shed, as well as on the roof of the house. Light-weight saw bar is a pair of steel plates that are bound inside with polyamide.
There is another group of chainsaws. those with interchangeable heads. It is necessary for chainsaws that are used in heavy cutting, when the rate of wear on mechanisms increases. For domestic needs, this form of tire is not necessary.
One of the important parameters of the saw bar, is its shank (attachment). Each manufacturer has a different tire mount. That’s why sometimes a guide bar from one chain saw may not fit on another.
Since the guide bar is directly connected to the chain that is mounted on it, it is important to consider the chain pitch. Find out what it is below.
What chain parameters influence chainsaw performance
The main performance characteristic of chain saws is performance, which is mainly influenced by engine power and the quality of the saw chain. When preparing the saw for work, it is also important to tuck it in correctly. First add any CU or JASO approved oil, and then add gasoline. The resulting mixture is mixed thoroughly. The choice of chainring is strongly influenced by the capabilities of the tool. When buying it, you need to pay attention to the marking, the correct deciphering of which will help to pick up the chain. The drive links and the chainsaw data sheet show these parameters:
- Chain pitch and size.
- Thickness of leading (shanks) and connecting links.
- Cutting depth and length.
- Number of cutters.
- Sequence of links. To install the right chain on a chainsaw, let’s break down these parameters in more detail.
Calculation of pitch and shank thickness
The pitch is the distance from one apex of the driving link to the other. To determine this parameter, it is necessary to measure the length between the axes of the two adjacent rivets, and the resulting figure in centimeters to convert it into inches, dividing it by 2.54. The larger the pitch, the more productive the saw is. But to pull chains with small pitch you need a more powerful motor to rotate the drive sprocket. Manufacturers produce chain products with the most common pitch sizes 1/4; 0,325; 3/8 (0,375); 0,404; 3/4. This value must be in line with the pitch of the drive and idler sprocket. However, there are non-standard saws, for example, Kalibr BP 220-18U, which has a pitch of 0.366. When a chainsaw is in operation, the main load is on the chain, the strength of which depends on the thickness of the shanks and connecting links. Measure with a caliper. For example, chain saw Kalibr BP-1800 has chain thickness of 1,3 mm. The thicker the links and the wider the guide bar groove, the stronger the chain. This chain requires a powerful chainsaw. The depth of cut determines the kickback while working and the cutting speed. It is directly proportional to the kerf.
How to know the size and height of the profile
profile height and number of cutting elements affects the depth of cut. The higher it is, the deeper the tooth goes into the wood being sawn, causing vibrations that wear out the chainsaw drive faster. Now you can buy low-profile and high-profile chain products. As a rule, chains with a low profile have a greater pitch and are mounted more often on household tools. Cutting length is comparable to the distance between the stop and the nose of the guide bar. It indicates how thick a trunk or piece of wood can be cut with the chain saw.
The number of drive links determines the size of the chain. Its size depends on the performance of the saw with an internal combustion engine and corresponds to the length of the bar. The technical data sheet shows the bar length that is appropriate for certain models of chain saw. To avoid breaking it, it is advisable to follow these recommendations. Sometimes, in order for a longer chain to fit a tire, it is shortened by removing a few links. This is forbidden, because it cannot be riveted on reliably with a handicraftsman, and it may break during operation, injuring people around you. However, the bar length does not determine the exact size of the chain product. Before buying it, its total length can be counted by taking it out of the package, by the number of shanks or connecting links. Not critical if there are a couple more links in the roll. The chain can be tightened with a tensioning mechanism.
Companies that make such equipment and parts for it produce chains in which the links are arranged in different sequences, which determines the efficiency of. Depending on the arrangement, there are these types of chains:
In chains of the first type, there are two shanks per cutting element. In products with a half-skip, the link in two is replaced by a connecting link, and with a skip. instead of every second cutter there is a connecting link. Skip chains have lower capacity and wear out quicker.
Chain types for chainsaws
Before you choose chains for your chainsaw, you need to consider their varieties. The elements in question are differentiated because of the classification of chainsaws, which come in household, professional and semi-professional. Before you buy a chain for your saw, you need to understand the available types of chainsaws.
Types of saw headsets
How to choose the device in question for your tool, not every professional knows. After the purchase of the tool, the need to buy and replace the saw chain does not appear until a few years later, provided that the chainsaw is in seasonal use. Not only chainsaws have the appropriate technical parameters, but also the saw headset. Both for chainsaws and electric saws it is necessary to select a chain, based on the technical characteristics of the tool. The main parameters of the devices under consideration are:
If you are the happy owner of a chainsaw (or an electric saw), then at a certain moment of the chainsaw use you will have a problem with the choice of the chain-set (the chain and/or the bar). And if at that point you don’t have an expert within reach to help you solve the problem, it can be a big problem.
The range of chains and bars for chainsaws (and electric) in a specialized store in Khabarovsk (or other region) can be huge and it can be easy to get confused. Let us help you find exactly what you need for your saw.
Chains, and therefore tires, have three basic characteristics:1. Length (for chain. number of links);2. Step (1/4″, 0,325″, 3/8″,,404″);3. Thickness of shank (for chain)/width of groove (for guide bar).
Knowing this information you can easily choose both the bar and the chain.
There are several articles on the Internet that detail all of these features. There is no sense in retyping all this material, especially since we don’t want to be accused of plagiarism)))). It is better to look at this information on the official website of the company
Below is a table with a selection of chains and bars Oregon by brand chainsaws that you can buy in Khabarovsk.
And also specified characteristics (in order number of links (pcs). pitch. groove width (mm)) on which you can easily pick up a saw set for your tool:
|Makita electric grooves 1.3 mm||UC3020A||12||45-3/8″-1,3||91-45||120SDEA041||120SPEA041||4,0|
|Makita Electric Groove 1.1 mm||UC3020A||12||45-3/8″-1,1||90-45||124MLEA041||4,5|
How to pick up
When it comes to choosing the optimal chain pitch for a chainsaw, it is best to take into account the manufacturer’s recommendations and choose the type of chainring on that basis.
If the manufacturer’s recommendations are not known, you have to choose according to the motor capacity. The recommended values corresponding to a particular pitch we have provided just above.
Important! When choosing, do not forget that the distance between the links, is not the only parameter to be paid attention to.
It is also worth selecting the thickness of the link, the type of cutting tooth, the number of links. Productivity largely depends on the angle of sharpening, cutting depth and the shape of the limiter tooth. The sharper the limiter tooth, the higher the cutting speed and the lower the quality of cut.

How to rule out the risk of buying a counterfeit chain?
On the domestic market there is a small but stable range of fake parts for chainsaws and accessories of Asian, mostly of Chinese manufacture.
Even if they want to meet the quality of the European level the technical and operational properties of the Chinese copies are far from being perfect, as they exhaust their resources by about 50-70%.
This disadvantage is compensated to some extent by the lower cost. On the other hand practice shows that long and trouble-free work of chainsaws guarantees only brand-name products.
Buying a part in a licensed or brand store will help you avoid the risk of buying a Chinese fake branded product.
