Description
Overview:
This Small End Bearing is a genuine Husqvarna OEM component for Partner/Husqvarna two‐stroke engines, used in heavy‐duty power cutters and professional chainsaws. It is a caged needle roller bearing that supports the connecting rod at the piston end (gudgeon pin/wrist pin location), keeping the top end running smoothly at high RPM. Precision‐ground, hardened steel rollers and a robust cage provide stable support and low friction under continuous load. Designed for demanding work, it restores and maintains smooth engine operation and helps protect the piston and conrod from premature wear. Ideal for Husqvarna K950 and K960 power cutters, and also selected pro chainsaws, this genuine part offers the correct tolerances and fit for reliable performance and long service life.
