Cylindrical roller and raceway are linear contact bearings.Load capacity is large, mainly bearing radial load.The rolling body and the ring baffle friction small, suitable for high-speed rotation.According to the ring with and without baffle, single row cylindrical roller bearings such as NU, NJ, NUP, N and NF, and double row cylindrical roller bearings such as NNU and NN can be divided.The bearing is a separable structure of inner and outer rings.
It is mainly used for large and medium-sized electric motors, locomotives, machine tool spindle, internal combustion engine, generator, gas turbine, reducer, rolling mill, vibrating screen and hoisting and transporting machinery
