Key Features
- OEM-Grade Precision Tolerancing — manufactured to Husqvarna's exact dimensional and hardness specifications, ensuring the rolling elements and raceway perform as the original bearing was designed to.
- Direct Drop-In Replacement — engineered to match the original bearing's geometry, so it seats correctly in the housing without rework or adaptation.
- Confirmed Fitment for K-Series Power Cutters — compatible with the K760, K760II, and K770, covering the most widely used models in this power cutter family.
- Sustained Rotational Efficiency — a correctly functioning needle bearing maintains precise shaft alignment and reduces friction under the high-cycle, high-load demands of cut-off saw operation.
- Verified OEM Part Number — cross-reference 577572401 against your machine's parts diagram to confirm the correct position before installation.
A needle bearing uses a series of small-diameter cylindrical rollers arranged in a tight radial pattern to support shaft rotation under high radial loads within a compact space. In a power cutter, this type of bearing is critical to maintaining smooth, accurate shaft movement — keeping internal components aligned and operating efficiently under continuous cutting loads. When a needle bearing wears or fails, it can cause increased vibration, shaft play, and accelerated wear on surrounding components, making timely replacement essential to restoring proper machine function.
