ISO 606 is the international standard for short-pitch precision roller chains. It defines chain dimensions (pitch, roller diameter, width, plate thickness) and minimum breaking loads for B-series (European) and A-series (American) chains.

What is the safety factor for roller chains?

Typical safety factors: 7-10 for normal operation, 10-12 for shock loads. Safety factor = Breaking load / Working load. Higher factors are needed for corrosive environments, high speeds, or critical applications.

How do I read a chain designation like 12B-1?

12B-1 means: 12 = pitch in 1/16 inches (12×1.5875mm = 19.05mm), B = European series, 1 = single strand. -2 would be duplex (two strands), -3 is triplex.

What is the difference between B-series and A-series chains?

B-series (ISO 606 European) chains have different roller diameter, inner width, and plate dimensions than A-series (ANSI American) chains of the same pitch. B-series generally have larger rollers relative to pitch. Always specify B or A when ordering.

How do I calculate chain tensile load?

Effective tension F = P/(v×η), where P is power in watts, v is chain speed in m/s, and η is efficiency (~0.97-0.98). The working load must not exceed the allowable tension (breaking load / safety factor).
