Convex Elasticity Shaft Coupler 4-10mm – D18 L38, 8-Set Screws, Encoder Motor Coupling

Got a project that needs a solid shaft connection?

This unbranded but totally reliable convex elasticity coupler works with shaft sizes from 4mm all the way up to 10mm.

It measures 18mm in diameter and 38mm in length, with 8 set screws to hold everything tight.

It’s brand new, still in its original packaging (though it might be a plain box), and unused.

Perfect for encoders, small motors, or any application needing zero backlash and a bit of vibration damping.

No fancy frills, just a solid little coupler that gets the job done.

MPN doesn’t apply—this is a straightforward, no-nonsense component.

If you’re tinkering, building, or replacing, this little guy’s got you covered.
