Safeware Authorized Supplier - AHL ST310SCJ7N - Sprckt & Rim Sys, Stihl, P .325, T7,R Y

Oregon Power Mate rim sprockets for chainsaws. Rims float on the splined hub of the drum and move side to side, allowing the chain and rim to align with the bar as the chain travels around the bar’s groove. The rim gets most of the sprockets wear, and by being replaceable, it extends the overall life and value of the sprocket system. This rim has wear depth indicators which tell you when to replace your rim.
