Abstract:
PROBLEM TO BE SOLVED: To provide a thrust roller bearing with races, for increasing an eccentricity allowance for a pair of relatively rotating members while securing a separation preventing function between a cage 3 and each of first and second thrust races 4a, 5a, increasing the amount of lubricating oil to be distributed inside, and actualizing the construction to be good in handling and to secure a stable operating condition under severe service conditions.SOLUTION: The outer diameter of an outer diameter side flange 8a formed at the outer peripheral edge of a first thrust race 4a is set to be 40-120 mm and the inner diameter of an inner diameter side flange 11a formed at the inner peripheral edge of an inner diameter side flange 5a is set to be 30-80 mm so that an internal clearance is 1-2 mm. For this purpose, outer diameter side lock parts 9a are formed at the front edge of the outer diameter side flange 8a intermittently with respect to the circumferential direction.
