Description

Chain coupling is composed of a duplex roller chain and two sprockets. The function of connection and detachment is done by the joint of chain. It has the characteristics of simplicity, high efficiency, easy-on and easy-off and nice outlooking.

It also has aluminium cover to prevent dust and protect the lubricant in order to extend the life of chain coupling.
