160 Roller Chain — Strand-Count Comparison
160 is ANSI B29.1 standard roller chain (ISO 32A), 2" pitch (50.8 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 160 share identical pitch, roller, pin, and plate geometry.
| Designation | ANSI 160 / ISO 32A |
| Pitch | 2" (50.8 mm) |
| Roller diameter | 1.125" |
| Width between plates | 1.25" |
| Pin diameter | 0.562" |
| Plate thickness | 0.25" |
| Plate height | 1.898" |

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.
