SKF 21245 Radial Shaft Seal

SKF 21245 Radial Shaft Seal is a rotating-shaft sealing component from SKF, identified by the part number 21245. Described as a CR (SKF) Radial Shaft Seal, this seal is designed to sit in a housing bore around a rotating shaft to form a sealing interface that retains lubricant and excludes contaminants from the bearing area. The radial seal type establishes a contact seal between shaft and housing, helping maintain a clean, lubricated environment for bearings and other interior components. It is used in mechanical assemblies with rotating shafts where a compact, reliable seal is required to minimize lubricant loss and protect against dirt, dust, and moisture intrusion. The 21245 designation places it within SKF’s line of radial shaft seals, providing a recognizable option for applications that require a maintained barrier around a rotating shaft.
