Radial shaft seal with metal case and SKF Wave lip, for oil or grease

A radial shaft seal, also known as a lip seal, rotary shaft seal, or oil seal, is a type of mechanical seal used to prevent the leakage of lubricants or other fluids in rotating machinery.

CRW1 seals feature a metal case, an SKF WAVE lip constructed from elastomeric material designed for enhanced pumping efficiency to minimize heat generation, and a garter spring to optimize the sealing performance against the shaft.

  • For oil or grease
  • With garter spring
  • WAVE lip creates higher pumping rate
  • WAVE lip has less friction between shaft and lip
  • WAVE lip has a lower temperature at the contact point
Type of outside diameter Metal-cased with sealant coating on the outside diameter
Lip material Fluoro rubber (FKM)
