48B Roller Chain — Strand-Count Comparison
48B is ISO 606 B-series roller chain, 3" pitch (76.2 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 48B 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.
