ABSTRACT:
This invention relates to an improved hanger bearing construction for auger conveyors and is directed more particularly to a sealed hanger bearing having improved service life. The device is characterized by the provision of frictionally driven wiper means which rotate with the shaft and prevent the ingress of contaminants into the interior of the bearing structure with consequent premature compromise of the bearing.
