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