This standard specifies a method for rating the pitting resistance and bending strength of open or semi-
enclosed gearing for use on cylindrical shell and trunnion supported equipment such as grinding mills,
kilns, coolers, and dryers. This includes spur, self-aligning spur, single helical, double helical, and
herringbone gears made from steel, ductile iron, and austempered ductile iron. Annexes cover
installation, alignment, maintenance, combination drives, and lubrication.
