description

  • Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. CRWHA1 seals are designed with a double metal case, an SKF WAVE lip made of elastomer with a 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.
