Product Description
Two-pitch transmission chain conforms to ISO 1275. ASME B29.100, DIN 8181 and JlSB1803.
The pitch of double-pitch transmission chain is twice that of short-pitch precision roller chain, and the other interchangeability dimensions are the same. The tensile strength and hinge supporting area of the double pitch roller chain are the same as those of the corresponding short pitch precision roller chain.
Compared with short pitch precision roller chain, double pitch transmission chain is lighter in weight, and is suitable for occasions with lower speed and longer transmission center distance.
Material:steel
