Abstract
A railcar adapter for the side frame pedestal of the truck assembly for a railcar. The adapter creates a clearance with the inboard and outboard lugs of the pedestal side frame to permit lateral movement of the adapter relative to the side frame. Plugs of a solid lubricant are provided on the crown of the adapter to facilitate movement.
Claims6
A bearing adapter for a railcar pedestal side frame having outboard and inboard lugs and a roof comprising
- an adapter body having an upper crown and a lower saddle for contacting a bearing element,
- said adapter body having a pair of opposed spaced lugs defining tracks for the outboard and inboard lugs of the pedestal side frame,
- said adapter body having means for permitting lateral movement of said adapter body relative to the roof of said pedestal side frame,
- said upper crown having a surface for contacting the pedestal side frame, said upper crown includes lubrication means for facilitating relative lateral movement between said adapter body and the roof of said pedestal side frame, said lubrication means being embedded beneath said at least one surface and having a portion exposed at said surface for reducing the friction of said surface, and
- said lubrication means releasing a lubricant over said surface through wiping action between said surface and the pedestal side frame during lateral movement.
