The standard selection method can be applied to most motor, steam turbine or engine drive applications


The following information is required for the selection of flexible couplings:

1.Power (kW) or torque (NM)

2.speed Application site or type of connected equipment (motor to pump, gear reducer to conveyor belt, etc.)

3.Axis diameter

4.Axial clearance

5.The limitation of the actual space

6.Information about special holes or completed holes and installation form


Standard selection methods are used in most cases. For these cases, use the selection method of the following formula


Formula selection method


The following process is used for:

1.peak load

2.Brake application (brake disc or wheel is an integral bid for the coupling, please contact the factory for design) Providing system peak torque and frequency, cycle period and brake torque will help to use the formula for selection more accurately.

Peak load: for motor applications with higher torque value than normal, for intermittent operation, impact load, In applications where the inertial effect caused by start-up or stop or repeated peak loads caused by the system is used, use the following formula. The system peak load is the maximum load that may exist in the system, and the rated load of the coupling is equal to or greater than the selected torque calculated according to the following formula
