A non-powered roller conveyor for conveying parts along a conveyor path includes a downwardly sloped conveyor support frame with a plurality of rollers rotatably mounted along the frame. The rollers comprise a length of prefabricated roller top conveyor chain mounted along a top surface of the conveyor frame. The conveyor chain includes a plurality of links connected together by pivotal connectors that permit sideways articulation of the links with respect to each other. Transverse rows of rollers are rotatably mounted on the links to permit products to roll along the conveyor. The rollers are easily replaceable when necessary. The conveyor follows a downwardly extending spiral path comprising a series of inclined straight sections interconnected by inclined bend sections. Both the straight and bend sections are inclined so that parts roll along the conveyor path under the influence of gravity.
