Reinforced american series roller chains

The roller chains of the reinforced American Series, not included in ISO standards, have an increased plate thickness (specifically, plate thickness is equal to the thickness of the plates of the ANSI normal chain of an immediately higher step), that makes these chains particularly suitable for applications subjected to pulse loads, with an increase of fatigue strength and the applicable load about 40% higher than the ANSI series. The ANSI H series, thanks to the increase of the working surface between pin and bush, has a better resistance to wear.
Both single and multiple rows of rollers are available.
