Ultimately, SKF caster bearings can eliminate induced axial loads, reduce risk of roll seizure, pro- mote enhanced bearing reliability and service life, and increase cast- er productivity. SKF spherical roller bearings feature two rows of patented self-guiding rollers with a com- mon sphered raceway in the outer ring and an optimized internal design. These features serve to reduce friction, mini- mize heat generation, accom- modate shaft misalignments and heavy loads, and contrib- ute to longer bearing life. SKF CARB toroidal types are self-aligning radial bear- ings merging the benefits of standard “locating/non-locat- ing” bearing systems typically found in continuous caster ap- plications. They are designed to accommodate misalignment (similar to spherical roller bear- ings) and normally supplied as full complement bearings to take advantage of their increased load rating.

The carbon-graphite components provide lubrication in most environments, and are designed for pumping liquids with poor lubricating qualities, strong chemicals that attack metals, and to pump air, vacuum, combustion products and gasoline vapors. Metallized Carbon’s carbon-graph- ite vanes, rotors, and end plates are used in such dry running applications as automotive anti-smog pumps and gasoline vapor pick up pumps, breath- able air pumps and vacuum pumps. In-liquid applications include vending machine beverage pumps, fuel and liquid chemical pumps, and medical liquid pumps. Metallized Carbon supplies the carbon-graphite vanes, rotor, and end
