Method for plating race-type assemblies

摘要

A method for converting an assembled, low-carbon-steel bearing of the double-race type of nickel-plated assembly having substantially the same dimensions throughout as the original bearing. The method is conducted with the bearing in the assembled state and comprises modifying all of the bearing surfaces by the steps of degreasing, chemically etching, chemically milling, chemically re-etching, and chemically nickel plating to replace with nickel the amount of metal removed by milling. During all but the re-etching step, relative movement is provided between the bearing races.
