ABSTRACT:
A rolling bearing used in a system including an automotive power train and a peripheral auxiliary equipment of the power train, and in a compressor. The rolling bearing comprises a first race and a second race. A rolling element is rotatably disposed between the first and second races. A film whose main component is a metal selected from the group consisting of nickel and copper has a thickness ranging from 0.1 to 15 μm. The film is formed on a surface of at least one of the first race, the second race and the rolling element.
