Description
Overview:
This genuine Stihl needle cage bearing is a compact, high-precision rolling bearing designed for high-revving chainsaw engines such as the Stihl 066 and 064. Built from hardened bearing steel, it withstands heat, load, and vibration while minimising friction between moving parts for smooth, reliable operation. Its dimensions are 10 mm x 16 mm x 13 mm (0.39 in x 0.63 in x 0.51 in), making it a direct-fit replacement where this size is specified. As a genuine Stihl part (MPN 9512 933 2382), it maintains correct clearances and alignment within the engine assembly, supporting performance and service life. Ideal for routine rebuilds or preventative maintenance, it helps restore efficiency and reduces the risk of premature wear in professional and domestic use.
