ABSTRACT:
A thrust bearing having a spiral element and a flat element is provided wherein both elements are arranged so as to be rotatable relative to each other and the spiral element is made completely of ceramics in a disk form having a pattern of spiral grooves on the surface thereof that opposes the flat element. The spiral grooves are formed by a shot-blasting process applied through a resin mask having a spiral pattern, the depth of the grooves being kept within a range of between 3 .mu.m and 50 .mu.m and the ratio of the outer diameter of the spiral element to the thickness of the spiral element being arranged to be aout 10: at least 0.4 or over.
