Carrying capacity: Angular contact ball bearings have high radial and axial load capacity. Especially under large axial loads, their advantages become more prominent. The load capacity and scope of use are determined by the contact angle of the bearing.
Contact angle: One key feature of angular contact ball bearings is the contact angle between the balls and the inner and outer rings. This angle is typically 15°, 25°, 30°, etc. A larger contact angle corresponds to a higher axial load capacity.
Adapt to high loads: Angular contact ball bearings are commonly found in applications requiring the ability to withstand both radial and axial loads, such as machine tool spindles, motors, and automotive bearings.
Withstand high speeds: Angular contact ball bearings utilize spherical rolling elements, which offer low friction resistance and enable operation at higher speeds.
Single row and double row: Single row angular contact ball bearings primarily endure axial loads in a single direction, whereas double row angular contact ball bearings can handle axial loads in both directions. Double row types are prevalent in applications demanding higher load capacities.
Preload: Angular contact ball bearings are frequently preloaded to enhance stiffness and load capacity. This preload can be achieved through the bearing assembly process.
Flexible application: Angular contact ball bearings can be customized with different angles and structures to suit various working environments and load requirements.
