Abstract
This method of manufacturing composite rings for rolling-contact bearings comprises the steps of making a composite ring from a blank of bearing steel sheet and a circular rough-shaped steel body obtained by compressing a same or different steel grade used in a granular, spheroidal, pulverulent or fibrous form, by means of a sintering, forging and/or rolling operation, the final product having the sheet portion disposed in the operative area of the ring.
