Rolling bearings are formed by disposing a crown of rolling bodies such as balls in contact with each other between a pair of concentric cylindrical deformable metal tubes, and then deforming the tubes toward each other on axially opposite sides of the balls by simultaneously exerting on the sleeves pressures directed toward the balls, thus utilizing the balls as forming elements for generating rolling tracks for the balls on the races provided by the sleeves. The sleeves are rotated relative to each other during this deformation by contoured forming rollers applied to the inner and outer surfaces of the inner and outer races, respectively. |
