Small sealed SKF Explorer spherical roller bearings with improved performance

Re-engineered for robust functionality

Small sealed SKF Explorer spherical roller bearings with improved performance have been at work in some of the world’s most advanced gearless traction machines for several years. New small sealed SKF Explorer spherical roller bearings with improved performance build on this robust functionality with an optimized seal design that slashes friction while keeping contaminants out.

Lower friction, lower operating temperature

With a new design that results in up to 50% less seal friction and 20% less total bearing friction, small sealed SKF Explorer spherical roller bearings with improved performance run with operating temperatures reduced by as much as 20 °C (36 °F) (diagram 1). 

This results in significantly longer grease life - up to twice as long as previous SKF bearings, reducing maintenance costs by extending relubrication intervals or even eliminating the need for relubrication altogether in some applications. In many cases, this will substantially reduce the total cost of ownership of the application.

Compact and built for speed

New small sealed SKF Explorer spherical roller bearings with improved performance have as much as twice the limiting speed rating of previous sealed SKF spherical roller bearings, making them highly suitable for today’s gearless traction machines and machine room-less designs, as well as pulleys and sheaves.

Benefits:

  • Twice the limiting speed rating through reduced friction
  • Significantly increased uptime
  • Lower operating temperatures through reduced friction
  • Extended relubrication intervals – up to twice as long
  • Relubrication-free in many applications
  • Reduced grease use and disposal costs
  • Less environmental impact

Applications:

  • Gearless traction machines
  • Pulleys and sheaves
