The paper contains data regarding the structural alternation of the material, the shape errors which appear and the roughness state of the bearing rings' surfaces obtained through the cold rolling proceeding to SC Rulmenti SA Barlad from Romania. We also present the simulation of the material's deformation in the 2D variant considering the directed flow on two directions. The cold plastic deformations gain advantage before the chip removal processings in the field of machine making, and that is why the present research refers to the throttling of the bearing rings, a modern proceeding, also applied recently in the mechanical engineering industry in Romania.

The paper is dealing with the measurement of the bottoming voltages which appear in the bearing race obtained through the new technology of cold rolling. The method of measurement is the tensiometrical method through the drilling on areas of the surface, achieved through the mts 3000 system of the hottinger baldwin messtechnik firm.
