Finer Power chain Coupling with Cover CC8020

These are chain couplings for joining two shafts, in sizes C4012 to C12022. Each coupling is two sprockets joined by standard duplex roller chain, and it is supplied complete with a cover. The compact design copes with some misalignment between shafts and is easy to fit and remove.

The sprockets are straight bore. It has a minimum and maximum bore for each size, and you have the coupling bored and keywayed to suit your shafts.

Choosing the right option

Choose the size from the torque and speed you need to transmit. Apply a service factor for the type of machine and the hours it runs before you check it against the rating.

Check the shaft sizes against the bore range for the size. Where a coupling runs above the speed shown for the cover requirement, the cover must be fitted. Spare covers are on Chain Coupling Cover Only.

Chain couplings are lubricated. Use the lubricant and interval recommended for the coupling and the speed it runs at. Align the two shafts as closely as you can before fitting the coupling, and check the alignment again once the coupling is fitted. Good alignment gives the longest life, whatever the coupling type.
