Cylindrical roller and roller ring is the line contact bearings. Loading capacity, mainly bear radial load. Rolling and the side of ring file with a small friction, suitable for high-speed rotation. According to the ring file under the ferrule can be divided into single row bearings such as NU, NJ, NUP, N, NF, etc. And double row bearings such as NNU, NN, etc...Cylindrical roller bearing's inner ring, outer ring is separable structure. No inner or outer ribs of the cylindrical roller bearings, the inner and outer rings can be relative movement to the axial, so you can use it as a free end of the bearing. One side of inner and outer rings has a double-side files, the other side has a cylindrical roller bearings of single file, can withstand a certain degree of axial load in one direction. General use steel stamping cage, or copper allow cage car system. But there are also parts of use forming polyamide cage.
