摘要：A constant contact side bearing assembly for a railcar including a housing withwall structure defining a central axis for the side bearing assembly and a multipiece cap.The cap is arranged in operable combination with the housing and includes a movablefirst member or spring seat and a movable second member or top cap carried by the firstmember. A spring resiliently urges the cap members toward railcar body structure. Thecap members define cooperating angled surfaces therebetween for urging wall structureon the first member and wall structure on the second member into frictional

engagement with the wall structure on the housing in response to a vertical load actingon the friction contacting surface on the cap. At least the top cap is structured toestablish a coefficient of friction ranging between about 0.4 and about 0.9 with the railcarduring operation of the side bearing assembly.
