ABSTRACT:
A rotary indexing table has a table defining a flat table surface. A dial having an upper surface and a lower surface is positioned over and generally parallel to the table surface. The dial further defines a circular inner edge and an outer edge. First bearings mounted to the table surface engage the inner edge of the dial to radially support the dial on the table. Second bearings axially support the lower surface on the table surface for rotation. The second bearings comprise circular grooves in the lower surface of the dial and concentric with the inner edge. Ball bearings are in the grooves and in contact with the flat table surface. A drive assembly comprising a belt engaging the outer edge and driven by a motor indexes the rotation of the dial.
