Product description

Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWA5 seals are designed with a metal case, an SKF WAVE lip made of elastomer with higher pumping rate to reduce heat generation. The seal also has a garter spring and a non-contacting auxiliary lip optimizes the sealing against the shaft.

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
