    摘要: A bearing (1) includes a cylindrical inner race (10); a plurality of rollers (13) arranged along an outer circumferential surface of the inner race (10); and a first cage (11) arranged radially outside of the inner race (10) to hold the rollers (13) on an outer circumferential portion of the inner race (10). The first cage (11) includes a plurality of first columnar portions (110) each of which extends in an axial direction, and a first ring (111) arranged to join axially upper end portions of the first columnar portions (110) to one another. The inner race (10) and the first cage (11) are arranged to rotate relative to each other. Each roller (13) is arranged between adjacent ones of the first columnar portions (110). A portion of each roller (13) is arranged radially outward of the first columnar portions (110). A second cage (12) is arranged between the first ring (111) and the inner race (10) and between the first columnar portions (110) and the inner race (10). The second cage (12) is defined by a solid lubricant.

    摘要: 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.
