SKF 28841 Radial Shaft Seal

SKF 28841 CR radial shaft seal is a rotating-seal component from SKF designed to fit between a shaft and its housing, helping retain lubricant while blocking dirt and contaminants from entering bearing cavities. The 28841 designation identifies this specific seal within SKF's CR radial shaft seal family, supporting reliable interchange with other SKF seals of the same geometry and performance class. Radial shaft seals like this one typically combine a metal carrier with an elastomer sealing lip that maintains contact with the shaft as it spins, creating a dynamic seal that protects gears, bearings, and other rotating components. The CR series designation points to a standardized seal design used across a wide range of equipment, enabling consistent mounting practices and compatibility with SKF housing bore specifications. Proper installation generally requires matching the seal to the housing bore and shaft surface finish, ensuring correct seating and lubrication retention to achieve reliable long-term sealing performance. Used in many industries where rotating shafts pass through a housing, SKF radial shaft seals help preserve lubricant integrity while preventing contamination, contributing to equipment reliability and reduced maintenance.
