Good quality, slow shipping
The coupling itself is great and holds torque well. Only downside was the shipping took a bit longer than expected.

Sturdy and reliable
Been using this for a CNC project for three months now. No signs of wear and vibration is minimal. Highly recommend.

Works as described
Does exactly what it should. The screws are good quality too. Would have given 5 stars if instructions were included.

Perfect fit for my servo motor
The machining quality is excellent. It fit perfectly on the lead screw and motor shaft without any wobble. Very satisfied with the rigidity.

Great value for money
Compared to other brands, this offers similar performance at a better price point. The flange design makes installation easy.
Q: Can this coupling handle a 10mm shaft diameter?
A: Yes, this series supports bore diameters ranging from 3mm to 20mm. Please select the specific model variant for 10mm.
Q: Is this compatible with stepper motors?
A: Absolutely. It is designed for servo motors but works perfectly with stepper motors and lead screws within the torque range.
Q: Is lubrication required for installation?
A: No, the diaphragm design is maintenance-free. However, applying a small amount of thread locker to the screws is recommended.
Q: What is the maximum misalignment tolerance?
A: The diaphragm type allows for slight angular and parallel misalignment, typically up to 0.5 degrees depending on the model.
Q: Do you provide an invoice for business purchases?
A: Yes, you can request a VAT invoice during checkout or by contacting our support team after purchase.
