Description

Oregon Power Mate® Rim Sprocket System – 34162XSF

The Oregon 34162XSF Power Mate® Sprocket System is a professional-grade drive solution for Stihl mid-range saws. This two-piece system consists of a clutch drum and a replaceable rim, offering a smoother cutting experience and significantly reducing chain wear compared to standard fixed spur sprockets.

Superior Rim Drive System

Unlike a spur sprocket, the rim-style system allows the chain to float on the spline, aligning itself perfectly with the bar groove. This self-alignment reduces friction and heat, extending the operational life of both your guide bar and saw chain. Because the drum is a separate piece, you can replace the rim multiple times before needing to replace the entire assembly.
