200 Roller Chain — Strand-Count Comparison
200 is ANSI B29.1 standard roller chain (ISO 40A), 2.5" pitch (63.5 mm). Compare all strand variants below — pitch and outer dimensions are identical across strands; load capacity scales roughly N× with strand count.
Shared Dimensions (all strands)
ANSI B29.1 pins these dimensions to manufacturer-independent values — single- and multi-strand variants of 200 share identical pitch, roller, pin, and plate geometry.
| Designation | ANSI 200 / ISO 40A |
| Pitch | 2.5" (63.5 mm) |
| Roller diameter | 1.562" |
| Width between plates | 1.5" |
| Pin diameter | 0.781" |
| Plate thickness | 0.312" |
| Plate height | 2.374" |

Per-Strand Load & Mass
Load capacity and mass scale roughly linearly with strand count. The sprocket must match (multi-strand sprockets carry N parallel tooth tracks). A dash (—) means the manufacturer doesn't publish that value for that strand variant.

Same-Pitch Cross-Series
Other chain families with identical pitch but different plate geometry — NOT directly interchangeable, but commonly mistaken for each other. The sprocket fits the pitch; the chain envelope differs.
