Abstract: A close tolerance disc for a flexible member conveyor including a disc body member and a movable resilient ring. The ring is preferably formed of a durable polymer interlocking ring where the ring outer periphery closely matches the inside surface of the conveyor tubing. The resilience of the ring biases it to conform to the inside surface of the conveyor tubing to provide 100% conveyance of the material in the system. The ring can move in place within a groove in the body member of the disc, as well as distort to self-align and conform to the irregularities that are present in the manufacturing of the conveyor tubular components. The ring is easily removeable for quick replacement and cleaning. The interlocking ends of the ring keep the ring ends in place and in line to prevent the ends from being misaligned while passing through a partially cutaway portion of the tube.
