The next information ought to be supplied to when placing an buy to guarantee the correct choice of the disc coupling:
Application and type of duty
Type of driver (engine, motor, turbine, and so on.)
Velocity and horsepower
Sort of driven
Shaft sizes and separation
Space limitations for major diameter and length
Type of match (Interference fit default, clearance match and shaft locking gadget preparation obtainable on request)
Distinctive specifications (vertical mounting, drop out center, flange mount, electrically insulated, API-610 as much as 3,800 RPM, shear pins, balancing, and so forth.)
Angular misalignment, axial misalignment, and rated torque are all associated to your coupling’s capability to accommodate application torque more than any period of time. As illustrated during the following charts, when the application torque increases to 50% of the coupling capability, the capability in the coupling to accommodate angular misalignment to is reduced. The same holds genuine for that ability to 
accommodate axial misalignment.
Variety Method
1. Select the coupling form.
2. Select the driven machine support factor SFA
3. Select the driving machine service factor SFD
Care need to be taken when the driving machine is other than a common electric motor or turbine. Some engines will impose added fluctuations about the drive technique and allowance really should be made accordingly. A torsional coupling may be essential for diesel drives.
