ABSTRACT OF THE DISCLOSURE A shock absorbing roller for mounting on a shaft having a central axis and for movement along a track, including a central hub portion for mounting the roller on the shaft, a roller portion surrounding the hub portion and including means interconnecting the peripheral roller portion and the hub portion and supporting the roller portion, and the roller portion including a flexible circumferential flange section extending outwardly away from the central hub portion and at an acute angle relative to an axial bore through the central hub portion for providing contact with the track and with the flexible circumferential flange section providing shock absorption and noise reduction on movement of the roller along the track. The roller is used as a part of a door assembly such as used for garage doors or truck doors and comprising a plurality of interlocked door panels. The roller is quieter in operation since it is shock resistant in other or both the vertical and horizontal directions. The usual loud clattering associated with such a door assembly is substantially eliminated when this roller is used.
