The Husqvarna 522839401 Bearing is a genuine OEM replacement designed for Husqvarna wall saws, including the WS440, WS440HF, WS482, WS482HF, and WS442. Sourced directly from Husqvarna, this bearing is manufactured to the same precision tolerancing as the original component installed at the factory. It installs directly into the confirmed fitment positions on these wall saw models with no alterations needed, restoring proper mechanical function and keeping your saw operating at full capacity. DHS Equipment supplies this genuine OEM part to help keep your equipment running without interruption on the job.
Key Features
- Precision-Toleranced OEM Construction — Manufactured to Husqvarna's exact dimensional and load-rating specifications, ensuring consistent rotational performance under the high-cycle demands of wall saw operation.
- Drop-In Replacement Fit — Engineered to match the original bearing's mounting interface, this component seats correctly in the WS440, WS440HF, WS482, WS482HF, and WS442 without modification.
- Broad Wall Saw Compatibility — Confirmed fitment across the WS440 and WS482 series, including both standard and HF variants, as well as the WS442, covering a wide range of Husqvarna track-mounted wall saw configurations.
- Restored Cutting Accuracy — A worn or failed bearing introduces vibration, misalignment, and uneven blade load. Replacing it with this genuine part restores smooth rotation and consistent depth control through the cut.
- Genuine Husqvarna Part — Cross-reference part number 522839401 against your machine's parts diagram to confirm the correct application before installation.
A bearing in a wall saw supports the rotating shaft or spindle, allowing the blade head to turn smoothly under load while maintaining precise alignment on the track-mounted cutting system. When a bearing begins to wear, operators typically notice increased vibration, irregular cutting performance, or unusual noise from the drive assembly — all signs that the component is no longer maintaining proper tolerances. Replacing the bearing promptly with a correctly specified OEM part like this one protects surrounding components from secondary wear and keeps the saw cutting true.
