Good value for money

Solid construction and works as advertised. It transferred the motion perfectly from the stepper motor to the lead screw. A reliable component for any serious hobbyist.

Sturdy and reliable

I've been running this on my machine for three months now at high speeds. No signs of wear or loosening. The anodized finish also looks professional.

Perfect fit for my CNC upgrade

This rigid coupling eliminated the wobble I was experiencing with my old flexible one. The aluminum alloy feels very solid and the direct connect design made installation a breeze. Highly recommended for engraving machines.

Great quality, precise machining

The build quality is excellent. It handles high torque without any issues. I deducted one star only because the instructions could be slightly more detailed, but overall a great product.

Solved my vibration issues

My engraver used to vibrate excessively at certain speeds. After installing this rigid coupling, the operation is smooth and quiet. Very satisfied with this purchase.

Zero backlash achieved

Exactly what I needed for my lead screw setup. The rigidity ensures that there is absolutely no play between the motor and the screw, resulting in much cleaner engraving lines.

5 FAQ

Q: Can this accommodate slight misalignment?

A: As a rigid coupling, it requires precise alignment between the motor shaft and lead screw. It does not compensate for angular or parallel misalignment like flexible couplings do.

Q: What is the maximum RPM this can handle?

A: Due to its rigid aluminum alloy construction, it is rated for high-speed applications typically found in engraving machines, safely handling up to 4000 RPM depending on balance and alignment.

Q: Do I need special tools to install this?

A: No special tools are required. Standard hex keys (Allen wrenches) included with your machine or a basic set are sufficient to tighten the set screws.

Q: Is this suitable for outdoor use?

A: While the anodized coating offers some corrosion resistance, this coupling is designed primarily for indoor industrial or hobbyist machinery environments.

Q: Does this coupling work with NEMA 23 motors?

A: Yes, this coupling is compatible with NEMA 23 motors provided the shaft diameter matches the inner bore size you select during checkout.
