Solid Build

Good coupling but delivery was slightly slower than expected. The quality of the aluminum is top notch and fits my motor shaft perfectly.

Excellent Precision

Used this for a servo upgrade on my lathe. The runout is minimal and installation was straightforward. Highly recommended for precision applications.

Works Well

Fits my NEMA 23 motor perfectly. Screws provided were good quality. Would have given 5 stars if shipping packaging was more robust.

Zero Backlash

Perfect for my CNC router project. No backlash observed during testing. The triple-disc design really helps with misalignment compensation.
