11139Radial shaft seal with metal case, SKF Wave lip and auxiliary, contacting lip, for oil or grease
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.
