When the desiredselection falls within the shaded area, consult Rexnord Industrial Chain for guidance.s Ratings are based on a service factor of 1. For a complete list of service factors, refer to Table 1, page C-7.The ratings listed above apply directly to lubricated, single strand, standard and heavy series roller chains.For multiple strand chains, apply the factors shown in the table at right. To select chains that vary in designor material from standard roller chain, use the factors in Table 3, page C-7.n Type A: Manual or drip (Maximum chain speed 130 FPM)Type B: Bath or disc (Maximum chain speed 1200 FPM)Type C: Forced (pump)Multiple strand factorsNumber of Multiple strandstrandsfactor2 1.73 2.54 3.35 4.16 5.07 or more Consult RexnordIndustrial ChainC - 27
