PRODUCT DESCRIPTION

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

Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWA1 seals are designed with a metal case, an SKF WAVE lip made of elastomer with higher pumping rate to reduce heat generation, a garter spring to optimize sealing against the shaft, and a dust lip to improve contamination exclusion. Most of the seals feature the SKF Bore Tite coating on the outside diameter that helps fill small imperfections in the housing bore.

  • 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
