Abstract:
Disclosed is a rolling bearing which contains no harmful substance and thus causes
no environmental contamination. Specifically disclosed is a retainer for rolling
bearings which is made of a cold-rolled steel sheet and holds a rolling element
of a rolling bearing. The retainer is obtained by subjecting the cold-rolled
steel sheet to at least one surface treatment selected from zinc electroplating,
tin electroplating, tin-zinc alloy electroplating, zinc-iron alloy electroplating
and zinc-nickel alloy electroplating, and then further subjecting the resulting
to a trivalent chromate treatment. The rolling bearing uses such a retainer for
rolling bearings.
