Low scope of application: double row short cylindrical roller bearing, suitable for machine tools on the high requirement of radial stiffness of the main shaft; Single row cylindrical roller bearing is suitable for machine tools on the radial stiffness and high demand for high speed spindle. For example, numerical control lathe spindle, CNC grinding machine for grinding wheel spindle, aircraft engine spindle, precision mechanical transmission, etc.
