Power Mate ® Rim Sprocket System
≥ 38 cc
This two–piece sprocket system is the ultimate way to drive the chain on most types of saws and can be used by all types of chainsaw users. • The complete sprocket system includes a clutch drum with spline and a replaceable rim sprocket. • The rim floats freely on the spline, maximizing chain-bar groove alignment for reduced wear and extended operational life. • The rim is replaceable which extends the life of the entire system and reduces overall costs. • The system provides smoother cutting and less chain jumping and wear. • Power Mate splines have either small (SM7) or standard (SD7) diameter.
