Performance classes

SKF Explorer bearings

In response to the ever-demanding performance requirements of modern machinery, SKF developed the SKF Explorer performance class of rolling bearings.
SKF Explorer spherical roller bearings realized this substantial improvement in performance by optimizing the internal geometry and surface finish of all contact surfaces, combining the extremely clean and homogenous steel with a unique heat treatment, improving the cage, roller profile and the geometry of the raceways.
These improvements provide the following benefits:
  • higher dynamic load carrying capacity compared to conventional design bearings
  • improved wear-resistance
  • reduced noise and vibration levels
  • less frictional heat
  • significantly extended bearing service life
SKF Explorer bearings reduce environmental impact by enabling downsizing and reducing both lubricant and energy consumption. Just as importantly, SKF Explorer bearings can reduce the need for maintenance and contribute to increased productivity.
The designations of SKF Explorer bearings are shown coloured blue in the product tables. The bearings retain the designation of earlier standard bearings. However, each bearing and its box are marked with the name “SKF Explorer”.
