Four row tapered roller bearings

Four-row tapered roller bearings can accommodate combined (radial and axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.These bearings are specially designed for rolling mill applications where their thin cross-section height and increased width provide higher capacity. The difference between a TQO bearing and a 2TDIW bearing design are relatively minor, as each uses two TDI cones.Built with highly rated Timken® tapered roller bearings, our sealed roll neck bearings are expected to provide a lower cost of ownership due to less required maintenance and longer bearing life. Timken case-carburized, high-capacity tapered roller bearings offer durable toughness.
