The next info must be supplied to when putting an buy to ensure the right selection of the disc coupling:
Application and style of duty
Form of driver (engine, motor, turbine, etc.)
Pace and horsepower
Variety of driven
Shaft sizes and separation
Space limitations for big diameter and length
Style of fit (Interference fit default, clearance match and shaft locking gadget planning out there upon request)
Unique requirements (vertical mounting, drop out center, flange mount, electrically insulated, API-610 as much as three,800 RPM, shear pins, balancing, and so forth.)
Angular misalignment, axial misalignment, and rated torque are all relevant to your coupling’s capacity to accommodate application torque more than any time period of time. As illustrated within the following charts, when the application torque increases to 50% in the coupling capability, the skill of your coupling to accommodate angular misalignment to is lowered. The same holds correct for your ability to accommodate axial misalignment.
Variety Method
1. Select the coupling variety.
two. Select the driven machine service component SFA
three. Select the driving machine support aspect SFD
Care needs to be taken once the driving machine is other than a regular electrical motor or turbine. Some engines will impose additional fluctuations to the 
drive method and allowance must be made accordingly. A torsional coupling may possibly be demanded for diesel drives.
