Are taper lock pulleys a good choice for ball screws?

[JeffZ]

I'm currently trying to figure out what the best way to install a HTD 5m pulley onto a 2010 ball screw is.
It will be driven by a 4.5Nm stepper motor through a closed loop timing belt.
This is what I have in mind:


One option would be to have the fixed end of the ball screw machined, either flat (into a d shaft), or into a keyway. This would accept standard AF/BF style pulleys with grub screws. However, I imagine that the loads of a Nema 34 motor are too high for a d shaft setup, and I'm not sure if keyway machining is a reasonable request.

During my research I've also come across taper lock pulleys. At first glance, they seem to be exactly what I need and don't require special ball screw end machining.
From what I've read, their disadvantage is that taper pulleys are large (start at 32 teeth) and heavy (steel).
My design can easily accommodate for the size, and I can't really imagine the weight of the pulley being an issue.



Unfortunately, I cannot find much information on people using them with ball screws.
Do you think that in my use case, taper lock pulleys are a good choice?

Thanks,
Jeff
