SKF Radial Shaft Seals

SKF radial shaft seals from the HMS5 and HMSA10 series conform to the sealing rings standardised in DIN 3760:1996 and ISO 6194-1:1982, with outer wrapping made of elastomer material, and are suitable for use in a very broad range of industrial applications, such as gears. The production range comprises sealing rings for metric waves of 6 to 250 mm, and therefore covers e.g. all sizes standardised in this size range in DIN 3760 and ISO 6194-1. Radial shaft sealing rings from SKF are excellently suited to sealing oil or grease-lubricated roller bearings. If the sealing lip also needs to be protected against penetration by dust and smaller solid contaminating particles, SKF recommends the radial shaft sealing rings from the HMSA10 series with protection lip.

Its key features and advantages are:

  • Optimised sealing material
  • Tension spring-loaded sealing lip
  • Optimally coordinated design of the sealing lip, membrane and tension spring
  • Grooved outer wrapping surface
  • Low-friction protective lip in HMSA10 design
