HK type roller chains conform to H (Heavy) type of ANSI, and their inner and outer plates are equal in thickness to those of the next larger size of standard roller chain. Therefore, the tensile strength is higher by approximately 20% and the maximum allowable load is higher by approximately 15% compared to D.I.D ANSI standard roller chain. However, since the weight of the chain is also larger, the performance at high speed declines. So, HK type roller chains are suitable for heavy duty at low speed.
