SKF Imported Wave Radial Shaft Seal, Housing Dia 77.75 mm, Width 7.95 mm

The radial shaft seals, also called SKF Wave seals as part of the CR Seals assortment, are low-friction seals with SKF WAVE lip design for reduced heat generation. For additional information, refer to the section Sealing lip design. They have a metal outside diameter for easy installation and a firm and accurate fit in the housing bore.

Radial shaft seals sit between rotating and stationary components, or two components in relative motion. They have two main parts. One is a cylindrical outer covering with an interference fit that seals statically against the housing bore. The second, a sealing lip, seals dynamically and statically against the shaft. Its sealing edge presses against the counterface surface of the shaft with a defined radial load.
