Abstract: A cage segment for a bearing rotatable around an axis being able to receive a plurality of rolling elements configured to travel on two annular raceways respectively on inner and outer rings of the bearing, and including an inner wall that extends circumferentially in the form of a cylinder, the axis of symmetry being the axis (X1), an outer wall that extends circumferentially in the form of a cylinder, the axis of symmetry being the axis (X1), two end portions that are circumferentially opposed, which extend radially with respect to the axis (X1) and which connect together the inner wall and the outer wall, a plurality of successive pockets for receiving the rolling elements, so that two successive pockets are circumferentially delimitated by a radial beam, The radial beam extending radially with respect to the axis (X1), the radial beam comprising two end portions so that one end portion connects with the inner wall and the other end portion connects with the outer wall, The radial beam provides a first rec

Abstract: An assembly arrangement between an inner race of a bearing and a journal supported in rotation in this bearing includes a journal annular groove and a race annular groove which interact to form an annular channel when they are placed opposite one another. The assembly further includes a retaining ring placed in the annular channel, which prevents a relative movement in translation between the journal and the inner race. The assembly also includes at least one recess of the journal and at least one tooth of the inner race, which interact to prevent a relative movement in rotation between the journal and the inner race.
