Our sprockets are available for most chainsaws in use today. We drive sprockets are available as either a one-piece “Spur” sprocket (shown on this page) or as a two-piecesprocket system which features a spline and free-floating rim (shown on our "Rim Sprockets” Features and Benefits sheet). The advantage of a spur-type sprocket is in its economy and its easy-to-use one-piece design. Bearings and other replacement components are also available from Durga Gears to help keep your sprocket in service for a long time.
