To manufacture a holding flange intended to be inserted into a groove of an outer ring of a rolling bearing, from a metal plate having a plate thickness measured between a front face and an opposite rear face of the metal plate, a method is performed in at least two steps. By penetration of a first tool, along a reference axis perpendicular to the plate and in a direction of penetration from the front face over an intermediate depth less than the plate thickness, the material initially located inside a front geometric envelope is pushed back into a volume axially located between the intermediate depth and the rear face of the holding flange and delimited by a blank geometric envelope. Next, by penetration of a second tool along the reference axis and in the direction of penetration, the plate is perforated to form a final bore having a rear geometric envelope located, in projection on a plane perpendicular to the reference axis, radially inside the front geometric envelope and outside the blank geometric envelope.

Method of manufacturing a flange for holding an outer ring of a rolling bearing

The invention relates to a bearing cage for a bearing of the type comprising a first ring having a first bearing race, a second ring having a second bearing race, rolling bodies positioned in an annular rolling volume between the first and the second bearing races in such a way as to enable a relative rotation between the first and second rings around a reference axis of the bearing, the cage comprising cells for housing rolling bodies, the cage being characterised in that it comprises an interface for coupling with a maneuvering member, such that when the maneuvering member is engaged with the coupling interface, the bearing cage is capable of being rotationally driven by the maneuvering member in a predetermined direction with respect to the reference axis.
