Key Features
- OEM-Spec Radial Load Tolerance — manufactured to Husqvarna's exact needle roller geometry and load rating, ensuring correct bearing pressure distribution within the assembly.
- Drop-In Replacement — matches the original housing bore and shaft diameter, allowing this bearing to seat correctly without machining or additional hardware.
- Broad Fitment Coverage — compatible with the WA20, RA10, RA10S, K1250, and K2500, spanning both construction equipment and power cutter applications.
- Restored Rotational Efficiency — a worn or failed needle bearing causes increased friction, vibration, and accelerated wear on surrounding components; this replacement restores smooth, low-friction rotation and protects adjacent parts.
- Genuine Husqvarna Part — sourced directly from Husqvarna's OEM supply chain, so the material grade, heat treatment, and cage design all match the original specification.
A needle bearing uses a series of thin, cylindrical rollers to support radial loads between a rotating shaft and its housing while occupying minimal radial space. Because the rollers have a high length-to-diameter ratio, this design handles high load capacity in a compact envelope — making it well suited to the tight assemblies found in power cutters and construction equipment. When a needle bearing wears, the rolling elements lose their precise contact geometry, leading to play in the shaft, increased heat buildup, and eventual damage to the surrounding housing or shaft journal.
