1.2 HIGH PERFORMANCE CHAINS These are enhanced types of ANSI Roller Chain (RS) in average tensile strength and/or fatigue resistance. Each chain has different features. Figure 1.2 shows the general relationship of high performance chains to ANSI Standard Roller Chain. NOTE: The multipliers shown in Figure 1.2 compare high performance chain to RS Roller Chain. The comparisons are between products of Tsubaki. You may find the ratio varies by chain size or manufacturer. Refer to a specific manufacturer’s catalog for details.
