Abstract
A door hanger assembly for a rapid transit railway passenger car includes an axially elongated generally cylindrical support shaft, and a door carrier assembly which includes a pair of bearing modules received and supported within opposite ends of a tubular sheath for rolling engagement with the support shaft and a door hanger depending from the sheath. Mounting members connected to opposite ends of the support shaft carry threaded fasteners for securing the hanger assemby to the frame of an associated rail car. Annular wipers and lubricant retainers carried by the bearing modules wipe and lubricate the support shaft as an associated sliding door carried by the hanger assembly moves between its open and closed positions.
