This type of bearings is separable bearings. Their contact angles are same as 35°. When received no load or pure radial load, the steel balls of the ball bearing contact with the four points of the rings. When it is received a pure axial load, the steel balls perform a two-point contact with the ring. In addition, besides the axial load from both directions, this kindly of bearing can take torque-load as well. 

Angular contact ball bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads. Furthermore, since an axial component is generated when a radial load is applied, these bearings are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets

 

Four-point contact ball bearings extensively used in: 

 Machine tool main shafts

 Mill grinding wheel shafts

 Internal-combustion engine liquid gear boxes

 Worm reduction gears

 Electric drillers

 Centrifugal machines

 Pressure boosters
