Exactly as described

Dimensions are accurate. The D19L25 size fits perfectly in the tight space of my prototype. No issues so far.

Perfect for my 3D printer upgrade

Fits the 5mm shaft perfectly. Very rigid yet flexible enough to handle slight misalignment. Highly recommend for 3D printing projects.

Great value

Bought these for a CNC spindle connection. They work smoothly without vibration. Fast shipping too.

Works but instructions lacking

The coupling itself is fine, but I wish there were torque specs included for the set screws. Had to look them up online.

Good quality aluminum

The build quality is solid. I ordered the 8mm bore and it matched my encoder shaft well. One set screw was slightly tight but manageable.
