Description
Overview:
The Needle Bearing for Husqvarna 334 and 335 chainsaws is a genuine Husqvarna component designed to support high‐speed rotating parts and reduce friction. Made from hardened steel with a caged needle roller design, it provides reliable load handling and smooth motion in compact spaces. This bearing helps keep drivetrain parts such as the clutch drum and sprocket assembly running freely, which maintains chain speed, reduces heat build‐up, and limits wear on mating surfaces. It is suitable for routine maintenance and repair on compatible Husqvarna petrol chainsaws, ensuring correct fit and consistent performance. As a Genuine Part, it offers assured compatibility and service life in demanding cutting tasks, whether used by tradespeople, grounds teams, or DIY users.
