The next information and facts needs to be offered to when putting an purchase to be sure the correct variety of the disc coupling:
Application and type of duty
Sort of driver (engine, motor, turbine, etc.)
Speed and horsepower
Style of driven
Shaft sizes and separation
Space limitations for significant diameter and length
Form of fit (Interference match default, clearance match and shaft locking gadget planning accessible upon request)
Specific demands (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 connected on the coupling’s capacity to accommodate application torque 
above any time period of time. As illustrated in the following charts, once the application torque increases to 50% in the coupling capacity, the capacity in the coupling to accommodate angular misalignment to is decreased. The same holds true for the capability to accommodate axial misalignment.
Selection Method
1. Select the coupling sort.
2. Select the driven machine service issue SFA
3. Select the driving machine support element SFD
Care needs to be taken when the driving machine is aside from a normal electric motor or turbine. Some engines will impose added fluctuations to the drive program and allowance needs to be made accordingly. A torsional coupling may perhaps be necessary for diesel drives.
