Selection tool for saw chain & guide bar

A "pitch" in saw chains refers to the distance between adjacent links of the chain. It is measured as the distance between three consecutive pivot points divided by two. Different pitch sizes are suitable for different types of chainsaws and applications.

 

The length of your cutting equipment is measured by the number of chain drive links, in inches (") or centimeters (cm).

The chainsaw usually has a certified range of cutting equipment lengths.

You can often find the length of the cutting guide on the beginning of the blade.

Example Husqvarna

You can read from this:
Item number: If you enter this with us on this website you will get the correct one right away.

Length: 15" / 38cm this is not the total length of the blade, but about what sticks out of the saw where you can really saw.

Pitch: 0.325"
Number of underbites: 64
Blade groove width: 0.50" / 1.3mm

Symbol next to groove width means that you can see at a glance that it is about a pixel blade or 1.3mm

Example Oregon

If you can't find the data. Due to wear on the blade, you can count the drive links on your chain. Then all you need to know is the pitch and thickness of the drive links

 

This is the thickness of the drive links and it is important to know this to ensure that the saw chain fits correctly in the guide.
The following thicknesses are possible:

0.043" / 1.1mm (usually pitch 1/4, 3/8LP or 0.325LP)
0.050" / 1.3mm (usually pitch 1/4, 3/8LP or 0.325 pixel)
0.058" / 1.5mm (usually .325 or 3/8")
0.063" / 1.6mm (usually 3/8" or 0.404")

The thickness, like the pitch, is probably displayed on the guide. If it is not or is no longer legible, use a caliper to measure the drive link on your old saw chain.
