The next details need to be supplied to when placing an order to be sure the correct variety of the disc coupling:
Application and form of duty
Variety of driver (engine, motor, turbine, and so forth.)
Velocity and horsepower
Variety of driven
Shaft sizes and separation
Area limitations for main diameter and length
Sort of match (Interference fit default, clearance fit and shaft locking gadget preparation out there upon request)
Specific prerequisites (vertical mounting, drop out center, flange mount, electrically insulated, API-610 as much as three,800 RPM, shear pins, balancing, and so on.)
Angular misalignment, axial misalignment, and rated torque are all linked on the coupling’s capacity to accommodate application torque in excess of any period of time. As illustrated within the following charts, when the application torque increases to 50% in the coupling capability, the skill of 
the coupling to accommodate angular misalignment to is reduced. Exactly the same holds genuine for your ability to accommodate axial misalignment.
Choice Method
1. Select the coupling sort.
two. Select the driven machine services component SFA
three. Select the driving machine support component SFD
Care need to be taken once the driving machine is aside from a typical electric motor or turbine. Some engines will impose further fluctuations about the drive process and allowance need to be manufactured accordingly. A torsional coupling may well be needed for diesel drives.
