Review on 🔄 Improved Diaphragm Coupling Coupler - Uxcell 10mm x 14mm by Andy Edwards

I installed several of these 10-14mm couplers to attach NEMA34 stepper motors to my 4" x 4" CNC router. I've used smaller screw couplings with NEMA23 stepper motors and could twist/damage them if the axis stalled. They hold up well - even when the axle hits the stops (during testing). I was a bit concerned that they don't have set screws that tighten on the shaft - rather, a screw on each end tightens a ring around the appropriate shaft. So far no problems.
