Good value for money

Solid construction and easy to install. The anodized finish looks professional. Took off one star because the installation manual could be more detailed regarding torque specs.

Great performance, precise sizing needed

Works exactly as described for our dual motor application. Just ensure you measure your shaft diameters carefully before ordering, as the fit needs to be precise.

Excellent for high-speed applications

Our testing rig runs at very high RPMs, and this coupling remains stable. The elastic diaphragm absorbs shocks effectively, protecting our sensitive motors.

Zero backlash operation

We replaced our old elastomer couplings with these diaphragm types, and the difference in precision is night and day. No backlash and very smooth operation at high speeds.

Durable and reliable

Been running this coupling in an industrial automation arm for three months now. It shows no signs of wear and handles the constant start-stop cycles beautifully.

Perfect fit for my CNC setup

The build quality is exceptional. The aluminum alloy feels robust yet lightweight, and the double diaphragm design handled the misalignment in my motor setup perfectly without any vibration.

5 FAQ

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

A: The single diaphragm model typically handles up to 1 degree, while the double diaphragm model can accommodate up to 2 degrees of angular misalignment, depending on the specific bore size.

Q: Is the material suitable for outdoor environments?

A: Yes, the aluminum alloy features an anodized surface finish that provides excellent corrosion resistance, making it suitable for most outdoor or humid industrial environments.

Q: Does this coupling require regular lubrication?

A: No, the diaphragm-type design is maintenance-free and does not require any lubrication during its operational life.

Q: Can I use the single diaphragm version for a dual motor setup?

A: While technically possible depending on alignment, we strongly recommend the double diaphragm version for dual motor setups to better compensate for parallel misalignment and reduce stress on the bearings.

Q: Do you offer custom bore sizes for non-standard shafts?

A: Standard sizes are listed in the catalog. For non-standard shaft diameters, please contact our sales team directly to discuss custom machining options and lead times.
