Abstract: The invention relates to a tilting segment (3, 3') for a tilting segment sliding bearing (1, 1') having a segment body (13, 13') for receiving bearing forces, wherein the segment body (13, 13') is made of a fiber-reinforced composite material. The invention is characterized in that the composite material comprises a polyether ketone, that the composite material has carbon fibers having a weight proportion of 25% to 70% as reinforcement fibers, and that the carbon fibers form a fabric that has a contour-parallel orientation to the sliding surface (8, 18) of the segment body (13, 13').

The two annular members have opposed surfaces each comprising hemispherical pockets that are formed at a plurality of positions in a circumferential direction of each of the two annular members and configured to receive balls. The opposed surfaces are snap-fitted to each other so as to couple the two annular members to each other. The hemispherical pockets each have an inner peripheral surface provided with a ball contact surface and a ball non-contact surface. The ball contact surface is formed at a central portion in a pocket circumferential direction of the inner peripheral surface and at least at a central portion in a pocket axial direction of the inner peripheral surface. The ball non-contact surface comprises a recess that is recessed to an opposite side to corresponding one of the balls across the ball contact surface. The recess is opened in at least one of pocket axial ends.

Abstract: A tapered roller bearing (31a) has a plurality of retainer segments (11a, 11d) each having a pocket to house a tapered roller (34a), and arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32a) and an inner ring (33a). The retainer segment (11a, 11d) is formed of a resin containing a filler material to lower a thermal linear expansion coefficient. In addition, a clearance (39a) is provided between the first retainer segment (11a) and the last retainer segment (11d) after the plurality of retainer segments (11a, 11d) have been arranged in the circumferential direction without providing any clearance. Here a circumferential range (R) of the clearance (39a) is larger than 0.075% of a circumference of a circle passing through a center of the retainer segment (11a, 11d) and smaller than 0.12% thereof at room temperature.
