Description
Overview:
This Genuine Husqvarna wheel bearing is a heavy‐duty, sealed ball bearing designed for selected walk‐behind lawnmowers, including the LC146S and LC351V. Made from hardened steel for strength and long service life, it supports the wheel hub and axle to reduce friction, improve rolling performance, and keep cutting height consistent. It is a direct replacement for worn or noisy bearings and helps restore smooth drive and steering on pedestrian mowers used for regular garden and grounds maintenance. Supplied to Husqvarna specification for fit and reliability, this bearing matches MPN 531208778 (OEM 531 20 87‐78), ensuring correct compatibility with listed models. A practical choice for routine servicing, it helps prevent premature wear of wheels and drive components.
