Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional and material specifications, ensuring the hub delivers the same structural integrity and load-bearing capacity as the original component.
- Direct Drop-In Replacement — Engineered to match the original mounting interface, this hub installs using existing hardware and mounting points with no rework required.
- Broad Floor Grinder Compatibility — Fits a wide range of Husqvarna floor grinders across the PG, HTC, and DURATIQ lines, including PG690, PG830, PG6P, PG8P, PG8D, DURATIQT6, DURATIQX8, HTCT8, HTCRX8, and more.
- Restored Drive Integrity — A worn or damaged hub compromises the connection between the drive spindle and grinding head, leading to vibration, uneven grinding, or tooling loss. Replacing it restores solid, centered power transfer.
- Verified OEM Part Number — Ordering by part number this part ensures you receive the correct hub for your machine — critical when working with multi-model equipment fleets across the PG and DURATIQ ranges.
The hub is the central mechanical interface that connects the machine's drive spindle to the grinding tooling or disc assembly. It transfers rotational force from the motor output to the working attachment, keeping the tooling centered and securely seated during operation. When a hub wears, cracks, or becomes damaged, the grinding head can wobble or detach, resulting in inconsistent surface finishes and potential damage to the machine or tooling — making timely replacement essential for maintaining safe, productive floor grinding work.
