Product Description


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 a high-speed environment .Because it cannot compensate for the relative displacement between the shafts due to high-speed operation. Of course, if the relative displacement can be successfully controlled, the rigid coupling can also play a very good performance in servo system applications. Especially the small specifications rigid couplings have the advantages of light weight, ultra-low inertia and high sensitivity.In practical applications, its have the advantages of maintenance-free, super oil resistance and corrosion resistance. Such as the GN rigid top wire series high-strength aluminum alloy coupling produced by our company has the above advantages.

Although people didn't think it was a good choice to use rigid coupling in servo system in the past.But due to its rigidity and zero clearance performance,  the small  aluminum alloy rigid couplings are used in the motion control field more frequently 


Integrated structure, the overall use of high-strength aluminum alloy material

High torque, high rigidity

The rigid type basically does not allow eccentricity, and it must be fully adjusted during use

Positioning screw fastening method


diaphragm coupling

Aluminum alloy coupling

See above pictures ,we can see it easily , even its not same design ,but we will make quality same as this level .there is no burrs ,no rust ,good surface treatment .we can offer different dimension and different technicial parametes  high performance aluminum alloy coupling,not only standard we also welcome Customize Aluminum Alloy Coupling,now let see the drawing and parameters of this flexible aluminum coupling .

The advantage of Gn jacking  aluminum  motor shaft coupling 

1. Light weight, ultra-low inertia and high sensitivity

2. Maintenance free, super oil and corrosion resistance

3. Aluminum alloy and stainless steel

4. Provide fastening bolt type, clamping type and separate type. We can produce bolt type (GN jacking series aluminum alloy coupling), or clamp type coupling (GNC rigid clamping series shaft coupling for motor), as shown below.

5 standard size in stock ,if  not big quantity ,we can delivery very fast within 3 days .

This is the Aluminum  alloy clamp rigid shaft coupling .
