Key Features
- OEM-Grade Sealing Material — Manufactured to Husqvarna's compression and material specifications, ensuring the seal performs correctly under the operating conditions of these floor grinders.
- Exact-Fit Replacement — Engineered to match the original seal profile, allowing it to seat correctly without modification to the housing or mating surfaces.
- Broad Floor Grinder Compatibility — Fits the PG680, PG680RC, PG820, and PG820RC floor grinders, covering both standard and remote-controlled variants in the PG series.
- Protects Internal Components — A properly functioning seal prevents contamination from slurry, dust, and debris from reaching internal assemblies — common hazards in concrete grinding environments.
- Leak Prevention — Maintains fluid or lubrication containment within the assembly, preventing the seepage that leads to accelerated wear on surrounding components.
A seal serves as a barrier between two mating surfaces or around a rotating shaft, preventing the migration of fluids, lubricants, or contaminants from one side to the other. On floor grinders like the PG680 and PG820 series, seals are critical to keeping grinding debris and water — generated during wet grinding — away from bearings, gears, and drive components. When a seal deteriorates or fails, contamination enters the assembly and lubricant escapes, accelerating internal wear and leading to more extensive component damage if left unaddressed.
