A railcar adapter for radially connecting a railcar body to a bearing. The railcar adapter includes an adapter body having two lateral channels each delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, lateral channels being adapted to cooperate with the railcar body. The railcar adapter also includes two frontal surfaces, an inner surface acting as a bearing seat for the bearing, and an outer surface. The railcar adapter provides two frontal flanges that inwardly protrude with respect to the inner surface, and that delimit with the inner surface a housing for the bearing, and at least one of the flanges is distinct from the adapter body and is mounted to a frontal surface of the body.

A railcar adapter for radially connecting a railcar body to a bearing. The railcar adapter includes two lateral channels each delimited by a pair of opposed lugs and a lateral guiding surface perpendicular to the opposed lugs, lateral channels being adapted to cooperate with the railcar body. The lateral guiding surfaces of lateral channels, in cross-section through a plane perpendicular to the axis of rotation of bearing, are curved.

The inner surface includes at least one central groove located on a first axis of symmetry of the railcar adapter emerging in each lateral channel. The inner surface further provides a second central groove located on a second symmetry axis of the railcar adapter, perpendicular to the first symmetry axis.
