QS 0000 642 1231
OEM rim sprocket from Stihl. Rim sprockets 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 sprocket wear, and by being replaceable, it extends the overall life and value of the sprocket system.
