Review on Uxcell Coupling L20XD12 Coupler Connector by Colin Watkins

Revainrating 5 out of 5

As advertised, great price, fast shipping, good fit and finish.

Most miniature shaft couplings have set screws that are 90 degrees apart. This is one of the few where the set screws are offset by 180 degrees. This makes it a more versatile stepper motor connector, allowing use with D, DD, and smooth shaft types. The workmanship is good, the fit is snug, shipping is fast, and the price is hard to beat.

Pros
  • The rigid type basically does not allow eccentricity and needs to be fully adjusted during use.
Cons
  • Very expensive
