Abstract

A pocket cage formed from a deformable sheet has a pair of side rings connected by a plurality of webs, each web having a projection comprising a folding of web material formed by bending at a plurality of bending points. At least the material in the middle of each web has reduced resistance to bending relative to the material in areas of each web other than the bending points. This folding is produced by applying opposing pressing forces on the front faces of the side rings using a tool. By placement of the middle bending point on either the outer surface or the bore surface of the web, the projection can be suitably selected to be radially inwardly or outwardly directed respectively.
