NU2200 Series

Single-row cylindrical roller bearings are designed with a separable structure that is comprised of both inner and outer rings, and feature a high load capacity that is suitable for large electrical machinery, machine tool spindles and gearboxes and more. Based on the different structures, we offer a variety of types, including the N-type, NU-type, NUP-type and NF-type. Users can choose the right bearing for their needs.

Types NU and N are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NUP can be used as fixed-end bearings.

Our recommendations are below, based on the different single row cylindrical roller bearing structures.

NU type Single Row Cylindrical Roller Bearings(RIU, RU)

Similar to N-type bearings, NU-type bearings only support radial loads, and an internal ring design with no ribs, and an outer ring design with ribs on both sides. NU bearings are suitable for use in compressors, pumps, mining equipment, transmissions and more. They are not ideal for trust load working conditions. In addition, there is only a small friction caused by axial displacement between two rings when the NU bearing rotates.
