Perfect for my CNC router
These couplings fit perfectly on my NEMA 23 motors. Very sturdy construction and the keyway alignment was precise.

Good quality
Solid aluminum build. The spider insert is a bit stiff initially but loosened up after use.

High torque handling
No slippage under load. Great for high-torque applications where belt drives are not an option.
