  • Angular contact ball bearing cage
    Patent number: 10247240
    Abstract: An angular contact ball bearing cage includes a plurality of pockets. At least one (imaginary) sectional plane extends through a first pocket, and the sectional plane is located such that an axis of rotation of the angular contact ball bearing cage lies in the sectional plane. The axis of rotation is an axis about which the angular contact ball bearing cage is configured to rotate in operation. A geometric centerpoint of the first pocket lies in the sectional plane, and an intersection of the sectional plane and a side of the first pocket includes a first portion that is not linear and that does not lie on the surface of a cone.
