The following information and facts ought to be supplied to when placing an order to be sure the correct variety of the disc coupling:
Application and variety of duty
Variety of driver (engine, motor, turbine, etc.)
Velocity and horsepower
Sort of driven
Shaft sizes and separation
Space limitations for key diameter and length
Form of fit (Interference fit default, clearance fit and shaft locking gadget preparation out there upon request)
Particular requirements (vertical mounting, drop out center, flange mount, electrically insulated, API-610 up to 3,800 RPM, shear pins, balancing, etc.)
Angular misalignment, axial misalignment, and rated torque are all relevant for the coupling’s capacity to accommodate application torque more than any time period of time. As illustrated while in the following charts, when the application torque increases to 50% in the coupling capability, the ability of your coupling to accommodate angular misalignment to is reduced. Exactly the same holds correct for that capability to accommodate axial misalignment.
Selection Process
1. Select the coupling form.
2. Select the driven machine services component SFA
3. Select the driving machine service component SFD
Care must be taken once the driving machine is aside from a typical electrical motor or turbine. Some engines 
will impose added fluctuations within the drive program and allowance should be produced accordingly. A torsional coupling might be essential for diesel drives.
