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.

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.

Zero backlash observed

Used for lead screw connection on a lathe upgrade. The bellows design compensates for minor misalignments effectively.
