Great value for the price

Works exactly as described. Installation was straightforward with the included screws. Deducting one star only because the shipping took a bit longer than expected.

Solid component

Does the job well. The star diaphragm design provides good flexibility for minor misalignments. Just make sure to measure your shaft diameter carefully before ordering.

Better than expected

Replaced an old plastic coupling with this aluminum one, and the difference in performance is night and day. Much smoother operation and less vibration.

Perfect fit for my CNC setup

This coupling fits perfectly between my servo motor and the lead screw. The build quality is excellent, and the aluminum feels very sturdy. Zero backlash noticed so far.
