Oregon OEP Power Mate Rim Sprocket System Sprockets

The Oregon Power Mate Rim Sprocket System is a replaceable-rim chainsaw drive sprocket (also called a rim sprocket or drum sprocket). It is built for smoother cutting and less chain wear than a standard spur sprocket. It suits homeowners, professional loggers and arborists.

Key Features:

• Two-piece design: a drum with a replaceable rim. You can change the rim several times before replacing the whole unit.
• Free-floating rim: the rim floats on the clutch drum spline, which helps the chain stay aligned with the guide bar and bar groove.
• Longer service life: better chain and bar groove alignment extends operating life and lowers overall running costs.
• Cold-forged construction: Oregon uses cold forging on its sprockets to improve durability and performance.
• Replacement guideline: for best performance, replace the rim every three rims. One sprocket typically lasts through two saw chains.

The sprocket pitch must match your saw chain pitch and, where fitted, your bar nose sprocket. Choose the pitch, tooth count and spline type that match your saw. Oregon offers bearings and other replacement components separately to keep your sprocket system in service.
