Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWA1 seals are designed with a metal case, an SKF WAVE lip made of elastomer with 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
