Four-point contact ball bearings
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
