SKF self-aligning bearing system

The new standard in locating and non-locating bearing arrangements

CARB toroidal roller bearing
In traditional locating and non-locating bearing arrangements, self-aligning bearings are generally used in both positions. While this arrangement accommodates shaft deflection, it does not enable full axial freedom. To provide full axial freedom, the non-locating bearing must be able to move with the shaft without creating unwanted internal axial loads. The CARB toroidal roller bearing offers this true axial freedom.

An innovative design, an ideal solution

SKF Explorer spherical roller bearing
CARB is a toroidal roller bearing that combines some of the best aspects of spherical, cylindrical and needle roller bearings. The rollers in a toroidal roller bearing always find the best position to accommodate the load, no matter how the shaft moves.

Intended exclusively as a non-locating bearing, CARB offers an ideal solution when used in combination with a spherical roller bearing in the locating position. With CARB as the non-locating bearing, the internal axial forces that can affect load distribution in traditional arrangements are avoided. 

Benefits of the SKF self-aligning bearings system:
  • Increased bearing service life
  • Extended maintenance intervals
  • Enhanced productivity
  • Lower running temperature
  • Lower vibration and noise levels

SKF Explorer performance class upgrade

All SKF Explorer spherical roller bearings and CARB bearings have been upgraded to the new SKF Explorer performance class specifications, featuring a combination of high-quality steel and an improved heat treatment process. The result: a superior balance between hardness and toughness, enabling up to twice the service life as the original SKF Explorer. Benefits of use include:
  • Increased uptime
  • Improved reliability
  • Resistance to contamination
  • Higher levels of productivity
  • Reduced noise and vibration levels
  • Excellent wear resistance
