The Husqvarna 502538801 Circlip is a genuine OEM component designed for PG680, PG820, PG680RC, and PG820RC floor grinders. As an authentic Husqvarna part, this circlip is manufactured to the exact tolerances required for proper retention and secure assembly within the machine. It is compatible across the PG680 and PG820 floor grinder families, including both standard and remote-control variants. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Retention Tolerance — manufactured to Husqvarna's exact dimensional specifications, ensuring the circlip seats and locks with the correct retaining force for this application.
- Drop-In Assembly Fit — engineered to match the groove dimensions of the original, allowing straightforward installation without reworking the housing or shaft.
- Broad PG Series Compatibility — fits PG680, PG680RC, PG820, and PG820RC floor grinders, covering both standard and remote-controlled models in these two grinder families.
- Restores Secure Component Retention — a correctly seated circlip keeps internal assemblies properly positioned during operation; a worn or missing one allows axial movement that leads to accelerated wear on surrounding components.
- Verified Part Number Cross-Reference — cross-reference part number 502538801 against your PG680 or PG820 parts diagram to confirm the correct fitment position before installation.
A circlip is a small but critical retaining fastener that sits in a machined groove on a shaft or inside a bore, preventing axial movement of the components it secures. In a planetary floor grinder like the PG680 or PG820, circlips are used throughout the drivetrain and gear assemblies to hold bearings, gears, and rotating elements precisely in position under the continuous load and vibration of surface grinding work. When a circlip deforms, slips out of its groove, or breaks, the retained component is free to shift, which can cause uneven wear, increased vibration, and eventual damage to adjacent parts if the issue is not addressed promptly.
