SKF Explorer spherical roller bearings

Continuous improvement to optimize bearing performance in the field

With improvements such as surface finishes and heat treatment, upgraded SKF Explorer spherical roller bearings can have a service life twice that of the previous industry-leading SKF Explorer bearings, especially under contaminated or poor lubrication conditions (Diagram 1 and Diagram 2).

Sealed bearings for superior protection against contaminants

Sealed SKF Explorer spherical roller bearings can significantly increase bearing service life in contaminated environments. These bearings are pre-lubricated with a specially formulated grease and sealed with highly effective contact seals. By eliminating or extending relubrication intervals, these bearings can significantly reduce the cost to purchase, apply and dispose of grease. Reduced maintenance costs will, in many cases, substantially reduce the total cost of ownership of an application.

Small sealed SKF Explorer spherical roller bearings with half the seal friction, twice the speed

With a new design that results in up to 50% less seal friction, small sealed SKF Explorer spherical roller bearings reduce operating temperatures by as much as 20 °C (36 °F) (Diagram 3), enabling us to double the limiting speed rating. As a result, more applications can benefit from the superior contamination protection of sealed SKF Explorer spherical roller bearings, including:

Additional benefits:

  • total bearing friction reduced by as much as 20%
  • relubrication intervals can be up to twice as long
  • grease usage can be reduced significantly
  • in many applications, the bearing can be considered relubrication-free for the life of the bearing, reducing maintenance costs
