ABSTRACT:
A water lubricated bearing or water lubricated seal using water as a lubricant. The bearing or seal has: a rotary member secured directly or indirectly to a rotary side, and a stationary member secured directly or indirectly to a stationary side and facing the rotary member for making sliding contact therewith. A substrate of either one of the rotary member and the stationary member is a metallic material and a thin titanium nitride film is formed on the sliding surface thereof. The other member is made of a non-brittle material or a film of hard material is formed on the sliding surface thereof. Thereby, a coefficient of friction of the bearing or seal is reduced and a wear resistance of the same is improved.
