    Application

    Cylindrical roller bearings have the characteristics of high load, low friction, high rigidity, and long life, and are widely used in heavy-load, high-speed, high-precision and other occasions.

    Motor field: widely used in large and medium-sized motors, generators, etc., can withstand the radial load generated when the motor is running, ensure the stable rotation of the motor shaft, and improve the operating efficiency and reliability of the motor.

    Mechanical transmission field: such as reduction boxes, rolling mills, vibrating screens, and lifting and transportation machinery, etc., can withstand large radial loads and certain axial loads, adapt to the transmission requirements under different working conditions, and ensure the stable operation of the equipment.

    Transportation field: used in the axle boxes and bogies of locomotives and vehicles, can withstand the huge loads and vibrations when the vehicle is running, and ensure the safety and stability of the vehicle.

    Installation and maintenance

    Due to its separable structural characteristics, installation and disassembly are relatively convenient. However, during the installation process, care should be taken to avoid damaging the raceway and rollers of the bearing, and the installation accuracy should be ensured to ensure the normal operation of the bearing.

    In terms of maintenance, the lubrication and wear of the bearing should be checked regularly, and the grease should be replenished or replaced in time. If abnormal wear or damage is found in the bearing, it should be replaced in time.
