Double Pitch Transmission Chains

Double pitch drive chain conforms to ISO1275, ASME B29.100, DIN 8181 and JIS B1803 standards.The pitch of the double-pitch drive chain is twice that of the short-pitch precision roller chain used for transmission, and the other interchangeable dimensions are the same. The tensile strength and supporting area of the double-pitch roller chain are the same as those of the corresponding short-pitch precision roller chain.
