SKF 48X72X7 CRSA12 R Radial shaft seal with metal case, double nitrile rubber 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 with an excluder 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.
