Abstract
A railcar adapter for radially connecting a railcar body to a bearing, and providing an adapter body. The railcar adapter includes two channel elements having each a pair of opposed lugs and a lateral guiding surface perpendicular to the opposed lugs so as to form lateral channels adapted to cooperate with the railcar body. The lateral channel elements are mounted in transverse grooves provided to transverse surfaces of the adapter body.
