PCT No. PCT/DE90/00805 Sec. 371 Date Jun. 20, 1991 Sec. 102(e) Date Jun. 20, 1991 PCT Filed Oct. 23, 1990 PCT Pub. No. WO91/06784 PCT Pub. Date May 16, 1991.A process for producing a rolling bearing cage with cast-on spring elements, in particular of a pinch roll free engine clutch, with a rolling bearing cage for guiding the rolling bearings. The cage is made by casting two rims, interconnected by several webs with parallel axes, onto each side of the rolling bearings. According to the invention, each spring element (7,8) is cast onto the corresponding web (4) by a large spring foot (14). Each spring foot (14) is used directly as a casting-on site (15) or the adjacent web or the region (16) between the spring foot (14) and the adjacent web (4) is used as the casting-on site (15). The flow cross-section of the spring foot (14) is greater than the flow cross-section of the spring elements(s) (7,8). The polymer material used is a self-reinforcing plastic containing liquid crystals.
