Description
Overview:
This small end needle bearing is a Non Genuine Part for Husqvarna two‐stroke engines, used at the small end of the connecting rod to support the piston pin and reduce friction. Built with hardened steel needle rollers in a robust steel cage (silver/grey finish), it helps keep the top end running smoothly under high RPM and heat. It is designed as a direct replacement for worn bearings in popular saws such as the Husqvarna 340 and 345, as well as the 350 and other listed machines. Fitting a fresh small end bearing helps restore smooth engine operation, protects the piston pin and con‐rod eye from wear, and supports reliable power delivery. Manufacturer reference: MPN 350 207.
