Bearing cage, radial bearing assembly with such a cage, in particular for a balancing shaft

A bearing cage for rolling element bearings, that is annular and centered on a central axis, the bearing cage comprising:

• a plurality of circumferentially adjacent pockets dedicated to each receive a rolling element, the bearing cage being split in the circumferential direction along a line of separation so as to define a first side and a second side that are circumferentially separated from each other, the first side and the second side having fixing means to fix the first side and second side to each other, wherein
• the fixing means comprises:
• at least one of the first and second sides comprising at least one projection extending in the circumferential direction towards the other side, the other side comprising a recess configured to receive the projection in the circumferential direction so as to fix the first side and second side to each other in at least a first direction,
• a concave portion extends in one direction from a first mounting surface defined on one of the at least one projection and recess, and at least two convex portions are provided on a second mounting surface defined on the other of the at least one projection and recess, the convex portions being circumferentially offset one to each other, the first and second mounting surfaces being mutually-opposable surfaces, and
• each of the convex portions is configured to receive the concave portion so as to fix the first side and second side to each other in at least the circumferential direction, the bearing cage having a different diameter when the concave portion of the convex portions is engaged with a different convex portion.
