The Husqvarna 593404501 Hub Assembly is a genuine OEM replacement designed for the HTC420VS floor grinder. As an authorized Husqvarna replacement component, this part is manufactured to the same specifications as the original, ensuring a correct fit and restored drive performance. DHS Equipment supplies this part to help keep your floor grinder operating at full capacity.
Key Features
- OEM-Matched Construction — Manufactured to Husqvarna's exact dimensional and material specifications, ensuring the hub seats and engages correctly within the drive assembly.
- Direct OEM Replacement — Designed to install in place of the original component on the HTC420VS with no adaptation required to mounting points or mating hardware.
- HTC420VS Floor Grinder Fitment — Verified compatibility with the HTC420VS floor grinder, so you can confirm fitment by cross-referencing part number 593404501 against your machine's parts diagram.
- Restored Drive Integrity — A correctly functioning hub maintains the alignment and torque transfer between the drive shaft and grinding head, keeping disc engagement consistent across the full working pass.
- Genuine Husqvarna Quality — Sourced directly through the Husqvarna OEM parts program, this assembly meets the structural load and wear demands of professional floor grinding applications.
The hub assembly serves as the central mounting and torque-transfer component connecting the drive shaft to the grinding disc or tooling head on the HTC420VS floor grinder. It bears the rotational load during operation and ensures the grinding head runs true and concentric. When the hub wears or becomes damaged, it can cause disc wobble, uneven surface finish, and accelerated wear on surrounding drive components — making timely replacement essential to maintaining grinder performance and surface quality.
