Good value, fast shipping

Solid construction and lightweight due to the aluminum alloy. Took off one star because the installation instructions were a bit sparse, but standard engineering knowledge applies.

Excellent torque transmission

We use these in our automated assembly lines. They handle high torque loads without any signs of wear after six months of continuous operation.

Precise and reliable

The double disc design provides great flexibility for misalignment while maintaining precision. Exactly what I needed for my robotics project.

Factory direct quality

You can tell this is factory direct pricing for the quality received. Much better than generic brands I have tried before.

5 FAQ

Q: Does this coupling require lubrication?

A: No, the Zheao diaphragm couplings are maintenance-free and do not require any lubrication during their operational life.

Q: Can I use this for high-speed applications?

A: Yes, the balanced aluminum alloy design makes these couplings suitable for high-speed servo motor applications commonly found in automation and robotics.

Q: Are custom bore sizes available?

A: We primarily stock standard metric and inch bore sizes. For large volume orders with custom requirements, please contact our sales team directly.

Q: What is the maximum angular misalignment this can handle?

A: Depending on the specific model size, our double disc couplings typically accommodate up to 1.5 degrees of angular misalignment. Please check the specific datasheet for your bore size.

Q: What is the difference between single and double disc types?

A: The single disc type compensates mainly for angular misalignment, while the double disc type can compensate for parallel, angular, and axial misalignments simultaneously.
