Bar & Chain Combos
Oregon Chainsaw Bar & Chain Combo
How do I measure the length of my chain?
- The length of your chain is determined by counting the number of drive links.
How do I know what size bar I have?
- Your bar's cutting length (or "called length") is different from its overall length. The cutting length is the distance from the front of the saw to the tip of the farthest cutter rounded to the nearest inch.
What is Chain Pitch?
- Chain pitch is the distance between any three consective rivets divided by two. Pitch defines the size of the chain. 1/4" is the smallest, 3/8" and .325" is the most common for hand held chain saws. For Harvester machines the pitch is usually .404" or 3/4". Other parts of the cutting elements are pitch related. The drive sprocket on the saw must be the same pitch as the chain, and so must the nose sprocket on sprocket-nose bars.
What is Chain Gauge?
- Chain Gauge is the Drive Link's thickness where it fits into the guide bar groove. The gauge of the chain and the gauge of the guide bar must match. Hand held chainsaws use either .050", .058" or .063" gauge.
What is the difference between 3/8" Low Profile and normal 3/8"?
- 3/8" Low Profile (sometimes called mini) chain is has a much lower profile and is used on lower powered homeowners chainsaws with 14" and shorter bars. Normal 3/8" chain is usually used for larger professional chainsaws with 16" and longer bars.
