CARB Circular Roller Bearings

CARB circular roller bearings are unique: not only can they withstand misalignment without increasing the stress level, but they also allow for frictionless axial movement within the bearing at the floating end in self-aligning bearing configurations. As JOJI bearings, they can withstand large radial loads, significantly extending their service life.

  • Can withstand misalignment and axial displacement within the bearing
  • High radial load carrying capacity
  • Enables frictionless axial movement
  • Long bearing life
  • Reduced noise and vibration levels
