Description
Overview:
This main bearing is a non genuine replacement for Partner/Husqvarna petrol cut-off saws, engineered to match the fit and function of OEM 503 25 00 01. Made from high-grade bearing steel with precision-ground raceways, it is used as a crankshaft main bearing to support rotating engine components and reduce friction under heavy load. It helps maintain smooth running, stable idle, and reliable performance in demanding conditions. Suitable for the K650 and K650 Active ranges, it is built for the harsh environment of construction and landscaping work where dust, vibration, and heat are common. A practical choice for routine engine rebuilds or preventative maintenance, it restores correct support at the crank and helps protect the seals and other internal parts from premature wear.
