Center Drive Spline and Rim Sprockets
The Oregon chainsaw center drive sprocket system was introduced after intensive research and testing. The Oregon chainsaw center drive replaceable rim type sprocket is the ultimate in design and strength. This system gives the professional smoother performance, faster cutting and economical use. Sprockets are fitted with the first drum and spline system manufactured from 100% steel for superior durability and come complete with an investment cast rim. In addition, Oregon spline hubs are double riveted to the sprocket drum thus giving a much stronger connection than copper brazing used by our competitors. The center drive system allows the user to change the rim sprockets when they become worn and also the chain pitch without having to change the entire system. All of these contribute to Oregon standard of excellence, making these sprockets the best available sprockets on the market.
