Good value for money

Solid construction and performs well under load. Delivery was fast. Only minor issue was the packaging could be better protected.

Perfect for CNC Retrofit

Installed this on my lathe retrofit project. The double diaphragm design handles the misalignment perfectly without any vibration. Very smooth operation.

Great performance, tight fit

Works exactly as described for my servo setup. The bore was a very tight press fit, which is good for precision but required careful installation.

Zero Backlash

Critical for my 3D printer upgrade. This coupling provides zero backlash and the elastic properties protect the motor bearings nicely.

5 FAQ

Q: How does the GND precision grade affect performance?

A: GND grade ensures extremely tight tolerances on the outer diameter and concentricity, resulting in minimal runout and higher positioning accuracy.

Q: Is this suitable for high-speed spindle applications?

A: Yes, the balanced aluminum alloy construction makes it suitable for high-speed applications commonly found in spindle drives.

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

A: This specific model typically accommodates up to 2 degrees of angular misalignment, though please check the specific datasheet for your bore size.

Q: Does this coupling require lubrication?

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

Q: Can I customize the bore sizes?

A: Standard sizes are listed in the options. For custom bore combinations, please contact our sales team directly for a special order.
