The Angular Contact Ball Bearings can bear both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and the line perpendicular to the bearing axis. High-precision and high-speed bearings usually take a 15-degree contact angle. Under the action of axial force, the contact angle will increase.
The Angular Contact Ball Bearings are suitable for Machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, indexing head, repair welding machine, low noise cooling tower, Electromechanical equipment, painting equipment, machine tool slot plate, arc welding machine etc.
Main Angular Contact Ball Bearings series: 7000C series, 7000AC series, 7000B series.Non standard bearing products can be customized according to application requirements.
