Radial shaft seal with double metal case, SKF Wave lip and auxiliary, non-contacting lip, for oil or grease
Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWHA1 seals are designed with a double metal case, an SKF WAVE lip made of elastomer with a higher pumping rate to reduce heat generation, a garter spring to optimize sealing against the shaft, and a dust lip to improve contamination exclusion. Most of the seals feature the SKF Bore Tite coating on the outside diameter that helps fill small imperfections in the housing bore.
- 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

Small diameter seals
I use a lot of small diameter inch dimension seals for the repair of older chainsaws. MRO is a great resource for many seals with very competitive prices and free shipping for larger orders. I will continue to use MRO whenever I can.
