The Husqvarna 584828401 Radial Seal is a genuine OEM replacement designed for the PG450 and HTC450 floor grinders. This seal is sourced directly from Husqvarna, ensuring it meets the exact material grade and dimensional tolerances of the original component. It installs directly into its mating bore without modification, restoring the sealing integrity your machine depends on. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- OEM-Grade Seal Material — manufactured to Husqvarna's compression and material specifications, delivering the sealing performance the original design requires rather than a generic approximation.
- Direct-Fit Replacement — dimensioned to match the original radial seal position exactly, seating correctly in its housing without rework or adaptation.
- Compatible with PG450 and HTC450 Floor Grinders — verified fitment for both the PG450 and HTC450 planetary floor grinder platforms, cross-reference part number 584828401 against your parts diagram to confirm your machine's configuration.
- Prevents Lubricant Loss and Contamination — a properly functioning radial seal keeps lubrication where it belongs and blocks debris ingress; a worn or failed seal leads to accelerated bearing wear and costly internal damage.
- Genuine Husqvarna OEM Part — supplied as an authorized replacement, ensuring the component meets the engineering standards set for the PG450 and HTC450 from the ground up.
A radial seal — sometimes called a shaft seal or lip seal — creates a dynamic barrier between a rotating shaft and a stationary housing, preventing lubricant from escaping while blocking contaminants such as dust, slurry, and moisture from entering the bearing cavity. In a planetary floor grinder like the PG450 and HTC450, this seal is critical to protecting the drive components that transfer power to the grinding heads. When the seal degrades or fails, lubrication bleeds out, abrasive material works its way in, and internal wear accelerates rapidly — making timely replacement essential to maintaining the grinder's output and longevity.
