ABSTRACT:
A sliding door assembly comprising a door hanger, a hanger sheave, an upthrust roller and a track, wherein the hanger sheave assembly and the uptrust roller are rotatably mounted on the door hanger. The track provides a first rolling surface for the hanger sheave and a second rolling surface for the upthrust roller. The track also preferably captures the upthrust roller thereby preventing the assembly from leaving the track.
