Abstract
A cage of a rolling bearing, the cage comprising: an annular heel centered on a central axis and having a constant radial thickness measured radially to the central axis; an axial portion extending from the heel substantially parallel to the central axis; and pockets delimited by the heel and the axial portion for receiving rolling elements. The axial portion has an axial length being greater than half the inner diameter of the pockets and an outside diameter being lesser than the outside diameter of the heel and which comprises between a first value equal to the pitch circle diameter of the cage minus half the radial thickness of the heel and a second value equal to the pitch circle diameter of the cage plus half the radial thickness of the heel. The pockets are spaced around the central axis having angular spacings being at least partly different from one another.
