Description
Overview:
This sprocket bearing is a non-genuine replacement for the drive system on Stihl chainsaws, designed to replace OEM number 9512 933 2260. Built with a hardened steel needle-roller assembly and robust cage, it supports the clutch drum and sprocket to reduce friction and wear during cutting. It is suitable for common homeowner and professional saws, including the Stihl MS170 and MS270, and many related models. Fitting a fresh sprocket bearing helps restore smooth rotation, reduces heat build-up, and protects adjoining parts such as the clutch drum and crankshaft stub. It is a practical maintenance item for saws that see regular use in pruning, felling, firewood processing, and landscaping.
