6.1.2 Nomenclature
Some chain manufacturers use their own nomenclature. In the case of Tsubaki, for example, chain size 16 with 200 mm pitch, is listed as RF12200-R. Here's what that name means.
- RF
- 12 — Average tensile strength, in tons, of the chain when it was originally designed
- 200 — Chain pitch
- R — Roller type
There are larger sizes than those shown in Table 6.1; in fact, tensile strength can exceed 4,460 kN! If you need extra-high performance chain, discuss the options with the manufacturer.
