SKF 24917 Radial shaft seal with metal case and double sealing lip, for oil or grease

Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. The seals have an outer covering of steel or elastomer, designed to fit the housing bore. The sealing lip is made of elastomer for best sealing against the rotating shaft. A garter spring in the seal optimizes the sealing against the shaft.
