description
- Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWH1 seals are designed with a double metal case, an SKF WAVE lip made of elastomer with a higher pumping rate to reduce heat generation, and a garter spring to optimize sealing against the shaft. Most of the seals feature the SKF Bore Tite coating on the outside diameter that helps fill small imperfections in the housing bore.
applications
- Engines
- Drive axles
- Transmissions
- Pumps

- Smaller pumps and general purpose machinery with pressured seal cavities
features
- For oil or grease
- With garter spring
- WAVE lip creates higher pumping rate
