The Husqvarna 502539501 Ball Bearing is a genuine OEM component designed for the PG680, PG820, PG680RC, and PG820RC floor grinders. As a direct Husqvarna OEM part, it is manufactured to the exact tolerancing and load ratings specified for these machines, ensuring a proper fit within the drivetrain assembly. This ball bearing is confirmed compatible with both the standard and remote-controlled variants of the PG680 and PG820 floor grinder lines. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM Precision Tolerancing — manufactured to Husqvarna's exact dimensional and load-rating specifications for consistent rotational performance in floor grinder applications.
- Drop-In Replacement Fit — engineered to the same dimensions as the original, seating correctly in the bearing housing without modification.
- Broad PG-Series Compatibility — fits PG680, PG680RC, PG820, and PG820RC floor grinders, covering both standard and remote-controlled configurations in the PG series.
- Smooth Power Transfer — a correctly functioning ball bearing maintains low-friction rotation in the drivetrain, allowing the grinder's tooling heads to operate at consistent speed and torque; a worn bearing causes vibration, heat buildup, and loss of grinding efficiency.
- Genuine Husqvarna Part — sourced directly from Husqvarna, part number this part matches the original component precisely, so you can cross-reference it against your parts diagram with confidence.
A ball bearing supports rotating shafts and spindles by reducing friction between moving parts, allowing them to spin freely under load. In a floor grinder like the PG680 or PG820, bearings are critical to maintaining smooth, consistent rotation of the drive system — directly affecting the quality and evenness of the grind. When a bearing begins to fail, operators typically notice increased vibration, unusual noise, or uneven tool head performance; left unaddressed, a worn bearing can accelerate wear on surrounding components and ultimately lead to drivetrain damage.
