SKF CARB Toroidal Roller Bearings

CARB toroidal roller bearings have one row of long, slightly barrel-shaped symmetrical rollers and torus-shaped raceway profiles. They are non-locating bearings and accommodate exclusively radial loads. CARB bearings are often used to replace the non-locating spherical roller bearing in a locating/non-locating bearing arrangement.


Here are examples of applications in which CARB toroidal roller bearings might be used:​

  • Industrial transmission
  • Metals
  • Pulp and Paper
  • Mining, mineral processing and cement
  • Industrial fans
  • Marine
Features and benefits
  • Accommodate misalignment
    CARB bearings are self-aligning like spherical roller bearings or self-aligning ball bearings.
  • Accommodate axial displacement
    CARB bearings compensate for thermal expansion of the shaft like cylindrical or needle roller bearings.
  • Wide assortment of dimension series
    CARB bearings are available with the same boundary dimensions as corresponding spherical roller bearings, self-aligning ball bearings, cylindrical roller bearings and needle roller bearings.
  • Long service life
    The special roller profile prevents stress peaks at the roller ends.
  • Low friction
    Self-guiding rollers keep friction and frictional heat at low levels.
  • Improved wear resistance
    All CARB bearings are upgraded SKF Explorer bearings.
  • Low noise
    CARB bearings can reduce noise and vibration levels, for example, in paper machines and fans.
  • Long bearing system life
    CARB bearings provide benefits in self-aligning bearing arrangements (fig. 7). With a CARB bearing in the non-locating position, there are no internally induced axial forces, which results in multiple benefits:
    • Less load extends the service life.
    • The bearings run cooler, the lubricant lasts longer and maintenance intervals can be extended.
    • Noise and vibration levels can be reduced.
