Cylindrical roller bearings mainly bear radial load.it is linear contact between roller and raceway.Rolling ring wall with small friction, Cylindrical roller bearing is suitable for high-speed rotation due to the small friction between rolling element and ring.According ring with ribs orwithout ribs , Cylindrical roller bearing can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The application of cylindrical roller bearing is Medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen, and lifting transportation machinery.
