CARB toroidal roller bearing with tapered bore (1:12)

CARB toroidal roller bearings are unique: as well as accommodating misalignment without increased stress levels, they also provide frictionless axial movement within the bearing in the non-locating position in self-aligning bearing arrangements.

Being SKF Explorer bearings, they can accommodate higher load levels and provide significantly extended service life.

  • Accommodate misalignment and axial displacement within the bearing
  • High radial load carrying capacity
  • Provide frictionless axial movement
  • Long bearing system life
  • Reduce noise and vibration levels
