A combination of a sliding-contact race (12) and bearing (10) in which a generally ring-shaped race member (12) and a generally ring-shaped bearing member (10) are fitted for relative sliding-rotation, the bearing member being within the race member. One of the members is comprised substantially of copper and the other of the members is comprised substantially of titanium. The members (10, 12) have lubricated contact surfaces (16, 18) for sliding-rotation, the member being comprised substantially of titanium having its lubricated contact surface being coated with chromium oxide (16).
