ABSTRACT
Several types of roller chains are used in conveyors. Many are of the single-pitch design covered in the ASME B29.1 standard, many more are double-pitch conveyor chains covered in ASME B29.4, and a few are hollow pin, covered in ASME B29.27. Small or large (carrier) rollers are available in the double-pitch series of conveyor roller chains; thus the chains can slide or roll on tracks or support rails. The conveyed material can be moved by bars, flights, slats, pusher lugs, and other types of components. The large and small roller types were shown in Figure 2-10 and Figure 2-11.
