Oregon Power Mate® Rim Sprocket System – 3/8″ x 7 Tooth (Stihl)
The Oregon 38470XSF is a high-performance two-piece drive system designed for professional Stihl chainsaws. By utilizing a free-floating rim on a splined drum, the chain is able to self-align with the guide bar groove. This floating action results in smoother cutting, reduced vibration, and significantly extended chain life compared to standard one-piece spur sprockets.
Cold-Forged Strength
Manufactured using Oregon’s specialized cold-forged process, the drum is engineered for extreme durability under heavy professional use. The modular design is cost-effective; because the rim is the only component that makes contact with the chain drive links, it can be replaced multiple times before the drum unit itself requires replacement.
