Coupling

Coupling is a core component that transmits power and motion from the driving shaft to the driven part while absorbing misalignment and any possible factors that could reduce efficiency of machines (e.g. vibration, noise, electric current, etc.)

A coupling type is selected mainly according to characteristic chart and types of connected motors. In case it is going to be used in a special environment e.g. vacuum, high-temperature, cleanroom facilities etc., please contact Sung-il Customer Service team in advance. As Sung-il Machinery manufactures products with various types of material, we may suggest an appropriate coupling considering the circumstance it is to be used.

The coupling`s outer diameter (OD) size is determined mainly by torque. The rated torque of a coupling has to be higher than the operation torque of a motor. The safety factor could be differently calculated by case/customer. The operation torque information can be easily found on the motor`s specification.

In case the operation torque should be calculated with operational P(Power Output) and N(rpm) values, please refer to the below formula.
