The Husqvarna 531111073 Bearing is a genuine OEM component designed for the DM406 concrete core drill. Sourced directly from Husqvarna, this bearing is manufactured to the exact tolerances required by the DM406, ensuring a correct fit without the guesswork of sourcing an off-spec alternative. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- OEM Precision Tolerancing — manufactured to Husqvarna's exact dimensional and load specifications for the DM406, delivering the tight clearances a drill motor bearing demands under sustained rotational stress.
- Direct Drop-In Replacement — engineered to the original mounting dimensions and seat geometry, so this bearing installs into the DM406 without modification to housings or adjacent components.
- Confirmed DM406 Fitment — verified for the DM406 concrete core drill, giving you confidence that part number this part is the correct specification for this machine.
- Sustained Rotational Support — a correctly fitted bearing maintains smooth shaft alignment and load transfer throughout the drilling cycle, supporting consistent torque delivery into the core bit.
- Genuine Husqvarna OEM Part — backed by Husqvarna's construction equipment supply chain, this is not an approximation; it is the same bearing specified for the DM406 on the factory parts diagram. Cross-reference part number 531111073 against your parts diagram to confirm before ordering.
A bearing in a core drill motor supports the rotating shaft under the combined radial and axial loads generated during drilling. It reduces friction between moving and stationary components, allowing the spindle to turn freely and transfer power efficiently to the core bit. When a bearing wears or fails, operators typically notice increased vibration, abnormal noise, reduced drilling speed, or excessive heat at the motor — any of which can accelerate damage to surrounding components if left unaddressed. Replacing the bearing with a correctly spec'd OEM part like this one restores proper shaft support and protects the integrity of the drill motor assembly.
