24B Roller Chain — Strand-Count Comparison

24B is ISO 606 B-series roller chain, 1.5" pitch (38.1 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)

ISO 606 pins these dimensions to manufacturer-independent values — single- and multi-strand variants of 24B share identical pitch, roller, pin, and plate geometry.

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.
