The Husqvarna 531073946 Ball Bearing is a genuine OEM replacement designed for the DM225 and DM225D concrete core drills. Sourced directly from Husqvarna, this bearing meets the exact tolerancing and load ratings specified for these drill motors, ensuring a correct, lasting fit. It is compatible with both the DM225 and DM225D models, making it the dependable choice when servicing either machine. DHS Equipment supplies this part to help keep your equipment running at full capacity on the job.
Key Features
- OEM-Grade Tolerance Precision — manufactured to Husqvarna's exact radial clearance and load specifications, maintaining the rotational accuracy that core drilling demands
- Direct Drop-In Replacement — engineered to match the original bearing seat dimensions, so this bearing installs into the drill motor assembly without modification
- Confirmed Fitment for DM225 and DM225D — verified for both concrete core drill models, taking the guesswork out of parts sourcing
- Sustained Drilling Performance — a correctly functioning bearing supports smooth, low-friction shaft rotation under the high axial and radial loads generated during core drilling; a worn bearing leads to vibration, heat buildup, and accelerated motor wear
- Genuine Husqvarna Part — carrying part number 531073946, this is an authentic OEM component, not an approximation, so fit and service life match the original design intent
A ball bearing in a concrete core drill motor supports the rotating spindle or armature shaft, allowing it to turn freely while managing the radial and axial forces generated during drilling. When the bearing is in good condition, the motor runs smoothly and efficiently with minimal heat and vibration. As a bearing wears — through normal load cycles, contamination, or inadequate lubrication — it develops play or roughness that increases friction, puts stress on the motor windings, and can ultimately cause motor failure if left unaddressed. Replacing a worn bearing with a correct OEM part restores the tight tolerances the drill was built around and protects the surrounding drivetrain components.
