SKF 21213 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 sealant coated double metal case. They have an SKF WAVE lip made of elastomer with a higher pumping rate to reduce heat generation. A garter spring in the seal and a non-contacting auxiliary lip optimizes the sealing against the shaft.
