Key Features
- OEM Precision Tolerancing — Manufactured to Husqvarna's exact dimensional and load-rating specifications, ensuring correct rotational performance and long service life in both cutting and drilling applications.
- Drop-In Replacement — Engineered to match the original bearing's dimensions and seating, allowing it to install directly into the housing without reworking or shimming.
- Broad Equipment Compatibility — Fits the DM280, DM340, and DMS280 concrete core drills as well as the K3000, K3000VAC, and K4000 power cutters — a single part number serving multiple machines in your fleet.
- Smooth, Low-Friction Operation — A properly functioning ball bearing keeps rotating shafts and spindles running true; a worn bearing leads to vibration, heat buildup, and accelerated wear on surrounding components.
- Genuine Husqvarna OEM Part — Supplied under the original Husqvarna part number 531073944, backed by the same quality standards applied to every component that leaves the factory.
A ball bearing supports and guides rotating shafts within the machine, reducing friction between moving parts and carrying both radial and axial loads during operation. In power cutters and core drill motors, bearings are critical to maintaining spindle alignment and smooth power transmission — keeping the cutting or drilling output steady and controlled. When a bearing wears, it typically introduces vibration, audible noise, and uneven loading that can damage the shaft, housing, and other drive components if left unaddressed.
