New bearings from SKF are engineered to support rollers in continuous caster applications at steel mills. The two types—spherical roller and CARB toroidal—help cope with axial expansion and contraction of rolls. The spherical roller bearings feature two rows of self-guiding rollers with a common sphered raceway in the outer ring. This reduces friction, minimizes heat generation, and accommodates shaft misalignments. The CARB toroidal bearings are self-aligning radial bearings that leverage the benefits of typical “locating/non-locating” bearings typically used in continuous caster applications. They accommodate misalignment and are normally supplied as full complement bearings to take advantage of their increased load rating.
