Application	cylindrical roller bearing is usually only subject to radial force. Compared with ball bearing of the same size, its radial bearing capacity is increased by 1.5-3 times. It is rigid and shock resistant. It is mainly used for large motor, machine tool spindle, engine front and rear support shaft, train bus axle, diesel engine crankshaft, automobile tractor gearbox, etc.
