There is a contact angle between the ferrule and the ball. The standard contact angle is 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the better the high-speed rotation. The single-row bearing can be used. Withstand radial load and one-way axial load, DB combination, DF combination and double row bearing can withstand radial load and bidirectional axial load. DT combination is suitable for one-way axial load, and the rated load of single bearing is insufficient. The high-speed ACH type bearing has small ball diameter and many ball numbers, and is mostly used for machine tool spindles. Angular contact ball bearings are suitable for high-speed and high-precision rotation. The two single-row angular contact ball bearings that are combined on the back side share the inner ring and the outer ring. The ring can withstand radial loads and biaxial axial loads, and the non-filled groove bearings are also sealed.

Mainly applicable cages: steel stamping cages (bowl shape...single row; S-shaped, crown-shaped...double row), copper alloy or phenolic resin cutting cage, synthetic resin forming cage.

Main uses: single row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft; double row: oil pump, Roots blower, air compressor, various transmissions, fuel injection Pumps, printing machinery.
