Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional and material specifications, ensuring the hub seats and loads correctly within the drive assembly without compromise.
- Direct Drop-In Replacement — Engineered to match the original mounting interface, this hub installs directly onto the machine using existing hardware and attachment points.
- Broad PG-Series Compatibility — Fits a wide range of Husqvarna PG-series planetary floor grinders, including the PG680, PG690, PG820, PG830, and their RC, P, and S variants.
- Restored Drive Integrity — A correctly fitted hub maintains proper alignment between the motor and grinding heads, ensuring consistent torque transfer and even surface contact across the grinder's working pass.
- Structural Durability — As a load-bearing hub on a planetary floor grinder, this component is built to withstand the continuous rotational forces and mechanical stress of production grinding environments.
The hub is a central load-bearing component in the floor grinder's drive system, connecting the motor output to the rotating disc or tooling carrier and transmitting torque to the grinding heads. It must maintain precise concentricity and a secure mechanical interface — any wear, damage, or improper fit at the hub can cause vibration, uneven grinding pressure, accelerated tooling wear, and loss of surface finish quality. Replacing a worn or damaged hub with a genuine OEM part restores the mechanical integrity of the drive system and returns the machine to accurate, consistent performance.
