Flexible Helical Shaft Coupling
For small torque shaft connection. Absorption of parallel, angular misalignments and shaft end-play by spring action
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
DIY Applications
Widely used in drive systems for encoders, instrumentation,lead screws, small pumps, feed rollers and anywhere light to medium duty, torsionally flexible coupling
CNC Machine
Flexible coupling suitable for model shaft connection, perfect accessories for RC Model motor, etc.
Robot Replacement
A special coupler, which can fix one shaft to a plane and install other parts on the shaft easily. Double connection points fasten the coupler tightly

Well made and the collet-style connection is really effective. Just know to have the set screw backed out before tightening collet clamp bolt. I need to bore the 12mm end to 1/2 inch (12.7mm) for my application. I did this using a lathe. Since having the coupler chucked in my lathe I could measure the run-out which was less than .001 inch. Good stuff!

I love the quality of this shaft coupling. Also, it has 2 grub nuts for each side which make for a better grip on the motor and shaft.

My 15+ year old exercise bike stand coupler broke (the one between the roller shaft and the resistance wheel). This got it up and running again. Excellent product.

Is coupling to care of a very slight out of alignment on my z axis. It is very well made and looks spectacularI'll buy another.

Great coupling! Machined with precision with just enough give for a CNC plasma machine. My cuts have never looked better and it only took a few minutes to install. I'll be using these for all my CNC coupling needs!

This needs a torque rating, it was completely unsuitable for my motors. Snapped almost immediately
