Abstract:
The present invention provides a rolling bearing which does not contain a hazardous substance and thus does not pollute environment. The present invention also provides a retainer, for holding rolling elements of the rolling bearing, which is made of a cold rolled steel plate. The retainer is subjected to at least one kind of surface treatment selected from among electrogalvanizing, electrotinning, electrolytic tin-zinc alloy plating, electrolytic zinc-iron alloy plating, and electrolytic zinc-nickel alloy plating. The retainer is further chromated with trivalent chromium. The rolling bearing uses the retainer for the rolling bearing.
