Rolling bearing retainer

A rolling bearing retainer (1) for a cylindrical roller bearing, which rolling bearing retainer (1) consists of two side rings (2, 3) which are connected to one another by axially running webs (4) uniformly spaced apart in the circumferential direction, so that pockets (5) are formed for accommodating cylindrical rollers (6), the webs (4) being at least partly twisted by being rotated by about 900 about their longitudinal axes (4.5), so that the cylindrical rollers (6) are prevented from falling out of the retainer (1), characterized in that a respective projection (4.3) is arranged in a center part (4.2) of the webs (4) on a circumferential side, and these projections (4.3), by twisting this web center part (4.2) about its longitudinal axis (4.5), are formed into holding lugs which, with regard to a bearing center point, extend in the bent-over state beyond a pitch circle radius (R) and in each case separate two adjacent cylindrical rollers (6) from one another and prevent the cylindrical rollers (6) from falling out in a radial direction, these radially oriented holding lugs, via two respective twisted parts (4.4) adjoining on both sides in the axial direction, being connected to a respective outer non-twisted web part (4.1), these web parts (4.1) being arranged outside the pitch circle (R) and preventing the cylindrical rollers (6) from falling out in the other radial direction.
