  • Railcar constant contact side bearing assembly
    Patent number: 8807050
    Abstract: A constant contact side bearing assembly for a railcar including a housing with wall 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 movable first member or spring seat and a movable second member or top cap carried by the first member. A spring resiliently urges the cap members toward railcar body structure. The cap members define cooperating angled surfaces therebetween for urging wall structure on 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 acting on the friction contacting surface on the cap. At least the top cap is structured to establish a coefficient of friction ranging between about 0.4 and about 0.9 with the railcar during operation of the side bearing assembly.
