Description
Overview:
The Needle Bearing for Husqvarna chainsaws is a genuine Husqvarna part designed to support smooth, low‐friction rotation in high‐speed assemblies. Built with hardened steel needle rollers in a compact cage, it resists wear and heat during regular and intensive use. This bearing helps keep the drive system running freely, protecting nearby components and maintaining cutting performance. It is a direct replacement for OEM No. 503 81 19-01 and is commonly used during clutch drum or drive sprocket servicing. Suitable for a wide range of Husqvarna petrol chainsaws, including the 242 and 246, it offers a precise fit that restores correct operation when the original bearing becomes noisy, rough, or seized. Ideal for routine maintenance and repairs.
