ABSTRACT:
A hinge and roller assembly for use in a roll-up door including a pair of leaves each forming a portion of a bearing socket, a bushing mounted in the bearing socket, a shaft slidably mounted in the bushing. The shaft mounts a roller on one end and the roller is adapted to roll in a track. A spring is mounted between the shaft and the bushing to bias the shaft axially toward the track. A releasable retainer on the bushing removably retains the bushing in the socket. Preferably, each of the leaves includes a plate through which the hinge is mounted to the door and an integral strap which is bent into a circular shape to define a portion of the socket and is attached at a distal end to the plate.
