Oregon Chainsaw Chain Types

Oregon Chainsaw Chains

Nearly all Oregon chainsaw chains are named by a part number made up of a number (indicating the chain's pitch & gauge, i.e. it's physical size), followed by one or two letters (indicating the chain's type, sequence and features), and finally (if it is a loop) another number (indicating the number of of drive links that the chain has).

e.g. 73 LPX 064E

Is a type 73 (.3/8" pitch, 0.58" gauge) low vibration chisel chain, with 64 drive links

The following tables will help you identify the type of Oregon chain your chainsaw is running.
