Key Features
- OEM-Grade Bearing Tolerancing — Manufactured to Husqvarna's precision load and radial tolerance specifications, maintaining the rotational accuracy critical for core drill performance.
- Direct Assembly Fit — Dimensionally identical to the original, this bearing seats correctly in the drill motor or stand housing without modification to mounting surfaces or retaining hardware.
- Confirmed Compatibility — Genuine OEM fitment for the DMS240 concrete core drill system and the DS250 concrete core drill stand.
- Sustained Drilling Accuracy — A correctly seated ball bearing keeps the spindle running true under load, preserving bit alignment and preventing vibration that can compromise core quality or damage surrounding components.
- Genuine Husqvarna OEM Part — Backed by Husqvarna's OEM supply chain, this component meets the same quality standards as the bearing installed at the factory, giving you confidence in the repair.
A ball bearing supports rotating shafts by reducing friction between moving surfaces, allowing the spindle or drive assembly to turn smoothly under the significant axial and radial loads generated during core drilling. When a bearing wears, develops pitting, or loses lubrication, the result is increased heat, vibration, and spindle play — all of which reduce core accuracy and accelerate wear on adjacent components. Replacing a failed bearing promptly with the correct OEM part restores smooth, precise rotation and protects the integrity of the surrounding drill assembly.
