ABSTRACT:
A roller assembly for use in gravity roller and power roller conveyors, especially those used in sanitary applications such as for food processing and the like. The roller assembly prevents contaminants from entrapment within the roller or associated parts and may be repeatedly washed or steam cleaned without corrosion or degradation. Preferably, wear-resistant, corrosion-resistant, organic, polymeric plastic, bearing inserts are axially and rotationally retained by retaining means within openings in the opposite ends of a corrosion-resistant roller. At least one of the roller end opening or the insert at each end includes a bottom wall closing off the roller interior and providing a thrust resisting surface. Preferably, the inserts receive stainless steel support shafts which have rounded ends engaging the bottom wall to resist axial thrust on the roller. In the preferred form, the bearing inserts have curved, shaft-engaging surfaces to facilitate and maintain low-drag, rotational support even when the roller is deflected during loaded operation.
