Abstract
Sliding material comprising a porous ceramic body that has the open pores filled with a high water absorbing resin, preferably to an open pores porosity of ca. 5-15%. The sliding material may be used to fabricate members of the stationary part of a journal bearing in a pump for use in both a fluid and a gaseous atmosphere; members of the rotating part of the bearing are formed of a cemented hard alloy. Since the resin absorbs and retains water, the sliding material will exhibit satisfactory performance even if it is exposed to a gaseous atmosphere without lubrication. Consistent sliding performance is insured not only in fresh water but also in fluids such as slurries that contain hard solid matter.
