Angular contact ball bearings

There is a contact angle between the ring and the ball. The standard contact angles are 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation. Single-row bearings can withstand radial loads and unidirectional axial loads. Structurally, two single-row angular contact ball bearings combined on the back share the inner and outer rings and can withstand radial loads and bidirectional axial loads.

Main uses:

Single-row: machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts.

Double-row: oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery.
