How to Choose the Right Coupling?

Flexible Jaw Coupling


Works stably and reliably, with good vibration reduction, buffering and electrical insulation properties.
It has large axial, radial and angular compensation capabilities, simple structure, easy installation, and is suitable for axial and radial installation.
It has good damping and vibration reduction characteristics, which can absorb some oscillation energy, reduce the oscillation amplitude when passing the vibration point, and reduce the torsional vibration stress of the shaft segment.
It has small radial size, light weight and small moment of inertia, and is suitable for medium and high-speed applications.
Special polyurethane elastic components have high wear resistance and oil resistance, large load-bearing capacity, long service life, safety and reliability.


Suitable for medium and high-speed applications, maintenance-free, and can be installed on machines that are inconvenient to disassemble. High wear and high grease working environment.

Disc Coupling


No lubricating oil is required, the structure is compact and the strength is high.
It has a long service life and no rotation gap.
It is not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance and corrosion resistance.


Suitable for shaft system transmission in high temperature, high speed, corrosive and medium working conditions.

Flexible Coupling


It is most suitable for correcting deflection angle and axial deviation, but its ability to handle eccentricity is relatively poor.
It also has the same impact on the rigidity of the coupling under torsion load. Excessive rotational clearance under torsion load will affect the accuracy of the coupling and impair its overall performance.


Suitable for light load applications, suitable for correcting deflection angle and axial deviation, and avoiding eccentricity using elastic couplings.

Rigid Coupling


If there is any deviation in the system, it will cause premature damage to the shaft, bearing or coupling, which means that it cannot be used in high-speed environments.
Unable to compensate for the relative displacement between axes caused by high temperatures generated by high-speed operation.
The small-sized rigid coupling has the superior performance of light weight, ultra-low inertia and high sensitivity.


If the concentricity of the shaft is high or the control is better, rigid couplings can perform very well in servo system applications. Super oil-resistant and corrosion-resistant, suitable for oily or corrosive environments.
