Ball retaining cage for ensuring circumferential spacing between balls of roller bearing of power steering of car, has cells presenting axial clearances, radial clearances and circumferential clearances along with balls placed in cells

摘要

The cage (5) has a set of cells (8) provided with an axial retention unit of the cage for axial retention on a ball (4) and another set of cells (9) deprived from the retention unit of the cage. The cells present axial clearances, radial clearances and circumferential clearances (J1c, J2c) along with the balls placed in the cells. The former set of cells is provided with spherical walls (7a), and the latter set of cells is provided with cylindrical walls (7b). An annular heel is prolonged axially by projecting portions, where the cells are defined between the portions.
