The Husqvarna 502539701 Radial Seal is a genuine OEM component designed for the PG680, PG820, PG680RC, and PG820RC floor grinders. Sourced directly from Husqvarna, this seal delivers the exact material grade and dimensional fit required to maintain proper shaft sealing on these planetary floor grinders. It is confirmed compatible across both the standard and remote-control variants in the PG680 and PG820 families. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- OEM-Grade Sealing Material — manufactured to Husqvarna's compression and material specifications, ensuring the radial seal performs correctly under the rotational loads and operating temperatures of a planetary floor grinder.
- Drop-In Replacement Fit — engineered to the original shaft and housing dimensions, this seal seats directly into position without modification or adaptation.
- Broad PG-Series Compatibility — fits PG680, PG680RC, PG820, and PG820RC floor grinders, covering both standard and remote-control configurations within these two popular grinder families.
- Protects Bearings and Internal Components — a correctly seated radial seal blocks contaminant ingress and retains lubrication, directly protecting the bearings and drive components that keep the grinder head running smoothly.
- Verified Genuine OEM Part — cross-reference part number 502539701 against your Husqvarna parts diagram to confirm the correct seal position before ordering.
A radial seal — also known as a shaft seal or lip seal — sits around a rotating shaft and forms a barrier between the internal lubricated cavity of the machine and the external environment. On a planetary floor grinder like the PG680 and PG820 series, this seal prevents grinding dust, slurry, and debris from entering the drive assembly while keeping lubricant where it belongs. When a radial seal wears or fails, contaminants reach the bearings and gears, accelerating wear and leading to costly internal damage; replacing it promptly with a correctly specified OEM part restores the protective barrier and extends the service life of the surrounding components.
