WRT is one of professional single-row(one-row) cylindrical roller bearings factory | manufacturer in China

Cylindrical Roller Bearing belongs to separable bearings, it is convenient to mount and dismount. they can be grouped into single-row (one-row), double-row, four-row series. Subject to the different rib, there are N, NU, NJ, NF an NUP series. It can accommodate mainly radial load, some single-directional bidirectional axial load owing to the structure of rib. Double row cylindrical roller bearings NN and NNU series own the compact configuration, strong rigidity and high loading capacity; most are used on machine tool spindles. FC, FCD and FCDP four-row series can endure big axial load and are mainly used on heavy machines for example rolling mills. Cylindrical roller bearings are mostly used on kinds of industrial machines .such as motors, machine tool spindles, oil machine, rolling mills, loading and moving machine
