The next info needs to be supplied to when placing an buy to ensure the appropriate collection of the disc coupling:
Application and kind of duty
Kind of driver (engine, motor, turbine, and so forth.)
Speed and horsepower
Kind of driven
Shaft sizes and separation
Area limitations for big diameter and length
Kind of fit (Interference fit default, clearance match and shaft locking device planning out there upon request)
Special needs (vertical mounting, drop out center, flange mount, electrically insulated, API-610 up to 3,800 RPM, shear pins, balancing, and so forth.)
Angular misalignment, axial misalignment, and rated torque are all associated for the coupling’s capacity to accommodate application torque above any time period of time. As illustrated in the following charts, when the application torque increases to 50% of your coupling capability, the skill of your coupling to accommodate angular misalignment to is decreased. The identical holds genuine to the capability to accommodate axial misalignment.
Choice Procedure
one. Select the coupling style.
2. Select the driven machine support component SFA
3. Select the driving machine support element SFD
Care really should be taken once the driving machine is aside from a typical electric motor or turbine. Some engines will impose additional fluctuations within the drive system and allowance ought to be produced accordingly. A torsional coupling may 
possibly be expected for diesel drives.
