Description

20X40X7 HMSA10 RG
Radial shaft seal with rubber outside diameter and single sealing lip, for oil or grease

Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. HMSA10 seals are designed with a rubber outside diameter. They have a conventional sealing lip made of elastomer. A garter spring in the seal and a non-contacting auxiliary lip optimize the sealing against the shaft also in polluted environments.

  • High pumping rate
  • Higher contamination exclusion with dust lip
  • With garter spring
  • Accommodates misalignment
