Key Features
- Genuine OEM Construction — Machined to Husqvarna's original dimensional tolerances, ensuring the bearing seats correctly and maintains precise concentricity under load.
- Direct Structural Replacement — Matches the original mounting footprint and bolt pattern of the factory housing for a straightforward installation on compatible floor grinders.
- Broad PG-Series Compatibility — Fits PG680, PG820, PG680RC, and PG820RC planetary floor grinders, covering both standard and remote-controlled variants in these families.
- Restored Shaft Stability — A correctly fitted bearing housing keeps the grinding head shaft running true, preventing vibration, uneven tool wear, and premature bearing failure.
- Durable Structural Integrity — Built from the same material specification as the original, this housing withstands the continuous rotational forces and contact pressures typical of heavy floor grinding work.
The bearing housing is the structural enclosure that locates and retains the bearings supporting the main drive shaft or planetary head shaft in a floor grinder. It holds the bearing in precise alignment so that rotational forces are transferred smoothly and evenly to the grinding tooling. When the housing becomes worn, cracked, or damaged, the bearing loses its correct seating, leading to shaft wobble, accelerated bearing wear, and a loss of grinding consistency — all of which can compromise surface finish quality and ultimately lead to more extensive drivetrain damage if left unaddressed.
