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. Our premium quality four-row sealed bearings are designed to operate at high speeds and withstand harsh environments, even while carrying heavy loads. Built with highly rated apered 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. high-capacity tapered roller bearings offer durable toughness. The newest sealed roll neck bearing is the integrated seal design that exemplifies our focus on advancing technology for the metals industry. Also available are the seal carrier design, many special designs and custom designs.

There are a variety of special features that can be incorporated in the design of four row bearings, such as: face notches, helical bore grooves, extended cones, re-lubrication accommodations, cup and/or cone seals, etc.
