Three row – roller

This bearing is comprised of an Inner Ring, Outer Ring, three rows of rollers and seals.  Three independent rows of rollers efficiently carry axial, radial and moment loads. With the most capacity per unit size this design also offers the highest stiffness and a low torque. The rectangular design allows for Internal, External, or no-gear designs.

Typical Capacity Range:
