The dual -section distance transmission chain meets the standards such as ISO 1275, ASME B29.100, DIN 8181 and JSB1803.

The spacing of the dual -section distance transmission chain is twice that of the short section of the transmission of the transmission. The tensile strength of the dual -section distance roller chain and the size of the chain branches are the same as that of the corresponding short -section distance. The dual -section distance transmission chain is lighter than the precision rolling chain of the short section, and it is suitable for occasions with low speed and long transmission center distance.
