By coping with axial expansion and contraction of rolls, SKF caster bearings can eliminate induced axial loads, reduce risk of roll seizure, promote bearing reliability and service life, as well as increase caster productivity. Spherical roller bearings have 2 rows of patented self-guiding rollers with common sphered raceway in outer ring and optimized internal design, while CARB® toroidal types are self-aligning radial bearings with locating/non-locating bearing systems' properties.
