Heavy Series roller chains differ from the ASME/ANSI standard series in the extra thickness of the link plates and the extra length of the pins. These link plates have the same thickness as the link plates of ASME/ANSI chains having the next larger pitch. The thicker link plates provide greater capacity (approximately 10%) for absorbing shock loads. These chains are suitable in situations where the load is heavy or operating conditions are severe.
