Radial shaft seal with metal case, double sealing 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. CRSA1 seals are designed with a single metal case, a single sealing lip made of elastomer for best sealing against the rotating shaft. The seal also has a garter spring to optimize sealing against the shaft and a dust lip to improve contamination ingress resistance.
