SKF 21358 Radial shaft seal with double metal case, SKF Wave lip, for oil or grease

Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWH1 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 optimizes the sealing against the shaft.
