The present invention provides a roller chain conveyor for use in bale movers and the like. The roller chain conveyor includes a pair of parallel a nd spaced apart, elongate roller chains which are arranged to support a bale thereon. The roller chain includes a plurality of links having side plates which are coupled together using pivot pins as in a conventional chain. A plurality of rollers having a diameter which is greater than a depth of the side plates of the links are rotatably mounted on the pivot pins respectively. Guards plates are mounted spaced abo ve each roller for supporting a load on a top side of the roller chain while permitting the rollers to rotate freely. The roller chains are thus supported for longitudinal rolling movement while supporting a load of bales thereon wherein the bales do not engage the rollers. Thus the bales are not damaged by the rollers and the rollers a re not subjected to the significant frictional resistance forces normally imposed b y the bales supported thereon.
