Cylindrical Roller Bearings are kind of separable bearings, it is convenient for mounting and dismounting. According to the row of its rollers, they can be grouped into single-row, double-row, four-row series.
Subject to the different edge, they have N, NU, NJ, NF an NUP series. It can accommodate mainly radial load and some single-directional and bi-directional axial load because of the edge structure.
Double row cylindrical roller bearings NN and NNU series have compact configuration, strong rigidity and load capacity, most 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 motors, machine tool spindles, oil machine, rolling mills, load and moving machine and kinds of industrial machine.
