Rolling bearing component e.g. inner ring, has metal layers of different compositions mettallurgically connected with each other by plated or rolling process, where component is made of strip material in non-machined manner

摘要

The component has metal layers (3, 4, 5) comprising different compositions and metallurgically connected with each other by a plated or rolling process, where the component is made of a strip material (2) in a non-machined manner. The thickness of the strip material is less than or equal to 0.2 millimeter. The metal layers (4, 5) are arranged on the metal layer (3) that comprises a cold deformable metal band.
