SKF offers bearing solutions engineered for support rollers in continuous caster applications at steel mills. The primary types of SKF caster bearings – spherical roller and CARB toroidal – serve to effectively cope with the axial expansion and contraction of rolls associated with induced axial loads and temperature fluctuations. Ultimately, SKF caster bearings can eliminate induced axial loads, reduce risk of roll seizure, promote enhanced bearing reliability and service life, and increase caster productivity.
SKF spherical roller bearings feature two rows of patented self-guiding rollers with a common sphered raceway in the outer ring and an optimized internal design. These features serve to reduce friction, minimize heat generation, accommodate shaft misalignments and heavy loads, and contribute to longer bearing life.
SKF CARB toroidal types are self-aligning radial bearings merging the benefits of standard “locating/non-locating” bearing systems typically found in continuous caster applications. They are designed to accommodate misalignment (similar to spherical roller bearings) and normally supplied as full complement bearings to take advantage of their increased load rating.
All SKF caster bearings are available in a wide range of sizes and can be specified with specialized seals and otherwise customized to meet demanding application requirements.
