Perfect for my CNC conversion
Fit perfectly on my NEMA 23 motor and lead screw. The keyway alignment was precise and there was no backlash during testing.

Excellent tolerance
Keyway was machined precisely to standard specs. Very happy with the rigidity and balance of the coupling.

Good quality, slight delay
Material feels solid and well-machined. Shipping took a bit longer than expected, but the product quality makes up for it.

Works as expected
Standard industrial quality. Installed easily on the shaft adapter. Would recommend checking bore size carefully before ordering.
