6.1.1 Standards
ISO 1977/1 ~ 3 includes standards for large pitch conveyor chains. These standards are for European-type chains, which have larger diameter bushings, pins, and rollers, and thinner, taller side plates than comparable sizes of chains made in the United States or in Japan.
Japan Chain Industry Association Standard JCAS 2-1982 governs seven categories of large pitch conveyor chains. The major characteristics of these categories are shown in Table 6.1.
| Chain Number (Pin Dia.) | Tensile Strength (kN) | Pitch (mm) | Side Plate | Inner Link | Roller Diameter | ||
|---|---|---|---|---|---|---|---|
| Height | Thickness | Width | Small | Large | |||
| 08 | 29.4 | 75~150 | 23 | 3.2 | 15.7 | 15.9 | 32 |
| 11 | 68.6 | 75~150 | 33 | 4.7 | 20.7 | 22.2 | 40 |
| 14 | 107.9 | 100~200 | 39 | 6.3 | 28.7 | 29.0 | 50 |
| 16 | 176.5 | 150~300 | 46 | 8.0 | 35.8 | 34.9 | 65 |
| 19 | 205.9 | 150~300 | 52 | 9.5 | 50.1 | 40.1 | 80 |
| 22 | 274.6 | 200~450 | 66 | 9.5 | 55.9 | 44.5 | 100 |
