SPROCKETS: The chainsaw drive sprocket moves the cutting chain around a saw's guide bar at high speed and are an essential element of the saw's cutting team consisting of the bar, chain, and sprocket. Oregon® offers a wide range of sprocket types for different sawing applications -- for professional timber cutters to homeowners who use saws to cut firewood and do chores around home. The ultimate drive-sprocket system is the Power Mate® system. Power Mate® provides you with:

• Smoother cutting
• More horsepower delivered from the saw
• Less chain jumping off the bar
• Reduced expensive chain wear

The system's rim-type sprocket can be replaced when necessary saving you money -- no need to replace the whole system.Oregon® sprockets can be installed on chainsaws having either inboard-clutch or outboard-clutch assemblies. Follow instructions in the operator's manual provided by your chainsaw manufacturer for correct sprocket installation.

Rim sprockets "float" on the splined hub, allowing chain and sprocket to self-align with the bar groove. The three most popular sizes are available in a radially ported design, which uses centrifugal force to throw off sawdust and debris.
