Abstract
A profiled cage characterized in that, between crossbars (5) in peripheral direction, side rings (1, 2) comprise a slot (15) which is spaced from the ends of the pockets (6) so that a section of material (16) is formed which is retained by two adjacent crossbars (5) and which, in a radially inwards bent state, constitutes the convexity (13, 14) providing an improved contact between the end faces of the rolling elements (7) and the convexities (13, 14).
Claims3
A radial cage for cylindrical rolling elements comprising side rings connected to each other by crossbars to form pockets, said crossbars being profiled so as to hold each rolling element on either side of a pitch circle by crossbar edges which are parallel to axes of the rolling elements, said side rings having inwardly directed convexities against which the rolling elements bear by end faces, wherein between the crossbars in peripheral direction, the side rings comprise a slot spaced from ends of the pockets whereby a section of material is formed which is retained by two adjacent crossbars and which, in a radially inward bent state, constitutes the convexity.
