The following information and facts need to be provided to when placing an order to be sure the proper choice of the disc coupling:
Application and form of duty
Type of driver (engine, motor, turbine, etc.)
Velocity and horsepower
Sort of driven
Shaft sizes and separation
Area limitations for key diameter and length
Variety of match (Interference fit default, clearance fit and shaft locking device 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 associated to the coupling’s capability to accommodate application torque more than any time period of time. As illustrated during the following charts, when the application torque increases 
to 50% on the coupling capability, the means in the coupling to accommodate angular misalignment to is lowered. The identical holds true to the ability to accommodate axial misalignment.
Selection Process
1. Select the coupling variety.
2. Select the driven machine services component SFA
3. Select the driving machine services element SFD
Care need to be taken once the driving machine is other than a common electric motor or turbine. Some engines will impose more fluctuations over the drive system and allowance needs to be created accordingly. A torsional coupling may be demanded for diesel drives.
