plastic metal working, possibly manufacture of bearing units. SUBSTANCE: method comprises steps of subjecting rolled metallic sheet to axially symmetrical cold deformation until achieving relative deformation value along any axis no more than 70%; blanking from metallic sheet washer restricted by coaxial circles; deforming said washer for making spheric portions for rolling bodies and flat portions arranged between spheric ones for punching holes for rivets; using as metallic sheet inner circle received at blanking retainers of large-size bearings; making one flat portion of retainer half on washer portion passing through radius being tangentially inclined by 45 degrees relative to texture of deformation caused by rolling process. EFFECT: metal economy, enhanced quality of products, enlarged manufacturing possibilities of method. 3 cl, 1 dwg, 1 ex
