Beam Shaft Coupling
Transmitting torque between two shafts while allowing for angular misalignment, parallel offset, and even axial motion, of one shaft relative to the other
Introduction of Shaft Couplings:
Know the Size You Need
We provide various kinds of rigid flange coupling for choosing. Please check the correct size: d1, d2, L, and D before purchase
Applications
Widely used in drive systems for encoders, instrumentation, lead screws, small pumps, feed rollers, and anywhere light to medium duty torsionally
Helical Parts
Absorption of parallel, angular misalignments and shaft end-play by spring action

I have tried several couplings for my CNC router and this one seems to be holding up better than the others. The fact that is is fairly solid with only a minor amount of give I think helps it be more sturdy.

Nice product. In using it on my 3d printer project.

I needed very tight tolerance on this part, and while i understand it's a cheap part, it wasn't very close. I had a motor hanging in space (supported only by it's shaft) acting as a regenerative brake. This meant any misalignment had the rotor oscillating around - not good. I ended up machining my own that was much more concentric and parallel.

Came with missing setscrew !! Cannot find M3 replacment with small enough head to fit. Complete waste of $

Coupling has a large amount of run-out (>.01") and the 5mm bore was not finished all the way down. Had to drill the last 1/16" of the bore to allow full insertion of the motor shaft. The clamping screws also do not provide sufficient torque for clamping to nominal shaft sizes. Both threads failed prior to the coupling locking onto the shafts.
