Angular contact bearing balls (type 70000 AC) with α=25°, are inseparable and can only bear the axial force of one side, and the shoulder heights on both sides of the inner and outer rings are different, so more steel balls can be loaded to improve the bearing capacity. Mainly used in a wide range of industries such as automobiles, electrical equipment, machine tools, and aircraft.
