How to Measure Chainsaw Bar
Your guide bar's length is represented by the cutting length (or "called length"), which is different from its total or overall length. The cutting length is the distance from the front of the saw to the tip of the guide bar, rounded to the nearest inch.
Tip: If you have an Oregon bar, look at the part number stamped on the motor end. The first two digits, such as 16, tell you the called length.
How Do I Measure the Length of My Saw Chain?
The length of your chain is determined by counting the number of drive links in your chain. A drive link is the saw chain component that guides the chain through the guide bar rails and around the sprocket. It is very important that the number of drive links are a match for the guide bar you are using since your chainsaw won’t function properly otherwise.
The drive link count is included in the saw chain part number, after the chain type designation (example, 20BPX066, H66). Common examples of drive length count are 70 for "D" or "72" chain and 56 for "S" or "91" chain.
Note: Your drive link count correlates to your guide bar’s overall size, which can vary by manufacturer. Oregon bars may take a different drive link count than that of another brand.
What is the Saw Chain Product Family?
Oregon understands that the need of woodcutters – professionals and novices – are as diverse as the terrains and environments in which they work.
We have organized our saw chains and guide bars into product families with key characteristics that different users will value. These product families will ensure that you choose the right chain and bar based on your everyday needs. It will make understanding the differences between our products effortless.
