Radial shaft seal with double metal case, SKF Wave lip and auxiliary, non-contacting lip, for oil or grease
A radial shaft seal, also known as a lip seal, rotary shaft seal, or oil seal, is a type of mechanical seal used to prevent the leakage of lubricants or other fluids in rotating machinery.
CRWHA1 seals feature a double metal case, an SKF WAVE lip constructed from elastomeric material designed for enhanced pumping efficiency to minimize heat generation, a garter spring to optimize the sealing performance against the shaft. Additional dust lip helps to improve contamination exclusion.
- For oil or grease
- With garter spring
- WAVE lip creates higher pumping rate
- WAVE lip has less friction between shaft and lip
- WAVE lip has a lower temperature at the contact point
