Key Features
- Genuine OEM Specification — manufactured to Husqvarna's exact dimensional and material tolerances for the hub position, ensuring correct load transfer and rotational alignment on the HTC420VS.
- Direct Replacement Fit — engineered to mount in the original hub position with no reworking of surrounding components, maintaining the integrity of the drivetrain assembly.
- HTC420VS Floor Grinder Compatibility — designed specifically for the HTC420VS floor grinder, so you can order with confidence knowing this hub matches your machine.
- Restored Drive Integrity — a worn or damaged hub can cause disc wobble, uneven grinding pressure, and accelerated wear on adjacent components; replacing it with this OEM part restores stable, centered tool rotation.
The hub is a central rotating component that connects the drive system to the grinding tooling on a floor grinder. It transfers rotational force from the motor to the grinding heads or disc, maintaining proper alignment and concentricity throughout operation. When a hub wears, cracks, or becomes damaged, it can introduce vibration, uneven grinding patterns, and stress on surrounding bearings and fasteners — making timely replacement essential to maintaining consistent surface finish quality and protecting the broader drivetrain.
