A thrust washer 100 for a flange half-bearing (220), the thrust washer 100 comprising: a substantially semiannular panel 102 having an inner edge 108 and outer edge; and hooking lugs 104 projecting inwardly from the inner edge 108 of the panel 102. The hooking lugs 104 have latching edges 118 that are configured to engage within corresponding openings (226) in a bearing shell (220) received by the thrust washer 100 and to prevent disconnection of the thrust washer 100 and bearing shell (220) without deformation of the bearing shell (220). Each hooking lug 104 has a hooking lug inner portion 104A proximate, around the inner edge 108 of the panel, to the central part of the thrust washer 100 for engaging against edges of the openings in the bearing shell (220) and a hooking lug outer portion 104B remote, around the inner edge 108 of the panel 102, from the central part of the thrust washer 100. The hooking lug inner portion 104A is thinner than the hooking lug outer portion 104B. Further optional features include parallel oil distribution grooves 110, 112 and a central stabilisation lug 106. |
