7928 Angular Contact Ball Bearing Short Description
7928 bearing, angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the line of contact between the ball and raceway in the radial plane and the vertical line of the bearing axis.
7928 Ball Bearing Features
Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can be relatively displaced along the bearing axis. This type of bearing is particularly suitable for bearing compound loads, that is, loads acting both radially and axially.



The axial load-bearing capacity of angular contact ball bearings increases with the contact angle α. The contact angle is the angle between the line of contact points between the ball and raceway in the radial plane and the vertical line of the bearing axis.

7928 Bearing Application
Single row angular contact ball bearings: machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, repair welding machines, Low-noise cooling tower, electromechanical equipment, coating equipment, machine tool slot plate, arc welding machine
