Oregon OEP 34162XSF Power Mate Rim Sprocket System Sprockets - 3/8 7-Tooth SM7

The Oregon OEP 34162XSF Power Mate® Rim Sprocket System is a professional-grade chainsaw sprocket designed for 3/8" pitch chains with a Small 7 (SM7) spline interface and 7-tooth rim. Engineered for all types of chainsaw users, this rim-style sprocket system delivers smoother cutting performance and reduced chain wear compared to traditional spur sprockets.

Key Features:

• Two-piece design — includes a clutch drum and a replaceable free-floating rim for extended service life
• Replaceable rim — the rim can be replaced multiple times before the entire unit needs replacement, maximizing economy
• Free-floating rim — allows the rim and chain to align naturally with the bar for optimal cutting performance and reduced wear
• Chain pitch: 3/8"
• Tooth count: 7 teeth
• Spline type: Small 7 (SM7)
• Compatible with Oregon replacement rims and bearings for ongoing serviceability

For best performance, Oregon recommends replacing the sprocket rim every three chains. Replacement rims, bearings, and other sprocket components are available separately from Oregon to keep this system in service long-term.
