Key Features
- Urethane-Grade Sealing Material — engineered from urethane for superior compression retention and resistance to the abrasion and fluid exposure common in planetary drive assemblies on floor grinders.
- Genuine OEM Specification — manufactured to Husqvarna's exact tolerances for the PG820 planetary system, ensuring the seal seats correctly and performs as the machine was designed to operate.
- Direct Fit for PG820 — designed specifically for the PG820 floor grinder, matching the original seal profile and dimensions for a straightforward installation.
- Protects the Planetary Drive — a properly functioning seal prevents lubricant loss and contamination ingress in the planetary head, preserving gear life and consistent grinding performance.
- Verified by Part Number — cross-reference 502534901 against your PG820 parts diagram to confirm correct application before installation.
The planetary seal in a floor grinder's planetary drive head serves as the barrier between the internal lubrication and the external grinding environment. It retains the gear oil or grease that keeps the planetary gears and bearings running smoothly while blocking slurry, dust, and debris from entering the assembly. When this seal wears, degrades, or fails, lubricant leaks out and abrasive contaminants work their way in — accelerating wear on the gears and bearings and ultimately threatening the integrity of the entire planetary head. Replacing this seal promptly with the correct urethane component restores the drive's protection and keeps the PG820 delivering consistent, controlled grinding output.
