Hi,

I´m looking for one coupler for my CNC. Not sure which one to choose...
Can any one help me ? If I'm not wrong one can not supply my torque... Suggestions ?

I have a fixed screw (only spin). Don´t think that will have axial movement ( but we never now this once is a home made cnc...).

The motor is a nema23 but with 2,5Nm - 354oz.
working at 1/8 - max velocity is 1400 p/min (is mm)
and acceleration in around 50.



What I´m looking for and doubt for the two types:


1. eBay item 260761797612

and the second model is:


2. eBay item 260756305564

My CNC table is around 63" x 47"
