  • Method of producing a workpiece having at least one bearing eye
    Patent number: 7178238
    Abstract: A method of producing a workpiece (1) having at least one bearing eye (2) is described, the bearing eye (2) being coated with an anti-friction coating (4), which forms a running surface deviating from a circular cylinder. In order to provide advantageous production conditions, it is suggested that the bearing eye (2) be processed for a precise fit to a circular cylinder, before the anti-friction coating (4) is galvanically deposited on the processed bearing eye surface (3) to form the running surface in a varying thickness which corresponds to the final dimensions.
