A thrust bearing 200 for use as a tram or a light rail coupling bearing is disclosed. The thrust bearing comprises a housing 201 having a base 205, a central post 207 upstanding from the base 205, and an inner ball 204 provided on the central post 207. An outer ball 203 is seated on and at least partially within the housing 201. At least one locking element 220 is arranged between the inner ball 204 and outer ball 203 so as to slidably retain the outer ball 203 in the housing 201. The at least one locking element 220 may have an outer bearing surface 221 and an inner bearing surface 222 that is in sliding arrangement with the outer ball 203 and the inner ball 202, respectively. A retainer 230 can be secured to the outer ball 203 to retain the at least one locking element 220. Optionally, a bearing insert 202 is arranged in the housing 201 to be in a sliding arrangement with the outer ball 203.
