CHAIN COUPLING
ROLLER CHAIN FLEXIBLE COUPLINGS
Nu-Teck Roller Chain Flexible Couplings are compact, all steel, long lasting flexible couplings, capable of transmitting relatively high torques with minimum space consumption. Consequently, they provide a most economical means of positive transmission of power from one shaft to another. The simple design and construction of these couplings make them extremely easy to install and disconnect, providing additional economy of operation.

SELECTION OF THE SIZE OF THE COUPLINGS
Decide the service factor for the unit for which the chain coupling is to be fitted by considering the following:
- Hours of service
- Type of power unit etc. from the following table
- For 8 to 16 hrs/day service, use the next step service factor.
- For 16 to 24 hours/day service, use service factor two step higher loading.
- Multiply horsepower of the driver unit by the service factor. This is design horsepower.
- Note the maximum rpm. at which the unit will run and its shaft diameter.
- From the H.P. rating table, select the coupling size which is rated equal to or slightly greater than design H.P. required at the rpm. at which the coupling is to operate.
- Also, make sure that the diameter at the shaft is less than the maximum bore permissible on the coupling. If the coupling is not large enough to accommodate the shaft size, use the next coupling which can be bored to suit the shaft requirement.
