The Power Mate Rim Sprocket System is the most effective way to drive saw chain on most chainsaws.
The Power Mate Rim Sprocket System includes a clutch cup with spline and a replaceable rim sprocket.
The rim floats freely on the spline, maximizing the saw chain-bar groove alignment.
The rim is designed to be replaced, maximizing operational life and reducing overall operating costs.
Note: All rim sprockets have two sets of teeth.
