I don't know much about Delta drives, but them seem to be recommended in many places. My spindle drive is delta and it is awesome! I have asked for some quotes from suppliers.

Is the ASDA-B2 series OK, or do I need the A2 series? They seem to use the same motors.

Unfortunately Delta don't offer a motor with a 19mm shaft. They have 22mm. I would need to replace the couplings. Currently it has rigid couplings with a keyway and grub screw onto the ball screw and a taper lock onto the motor shaft. The Delta motor is 22mm keyed. What is the recommended type of coupling for such a retrofit?

Flexible type coupling

rigid couplings are a big no no.
use typical cnc couplings like these.

or china version

Are they OK for higher torque and acceleration? No risk of oscillation in the flexible part on high speed moves?

I need to measure the size on the machine today. I didnt see any 22mm couplings but will look again tonight once I know the size for the other end.

Thanks, I hadn't seen those documents and would have just worked it out! I got them from Alibaba as you suggested. I have not received them yet but if it turns out the supplier is good I will share his details. He was very knowledgeable and excellent to communicate with.
