Description
Overview:
This Needle Bearing is a genuine Husqvarna component for the clutch drum/sprocket assembly on selected Husqvarna chainsaws, including the 545 and 555. It uses a cage of precision needle rollers in hardened steel to provide low-friction rotation between the clutch drum and the crankshaft journal. By reducing friction and wear, it helps the saw start cleanly, idle smoothly, and deliver consistent drive to the chain under load. Built for daily use in demanding conditions, it is suitable for professional forestry work and general cutting tasks. Manufactured to Husqvarna's tolerances for correct clearances and alignment, it is a direct replacement part and fits without modification. Genuine Husqvarna Part MPN: 503253401 (also listed as 503 25 34-01).
