This version has a 20mm ball screw with a 5MM lead, but can go up to 25mm diameter with any lead.
We are also working on a smaller version that uses a 16mm ball screw, so will be a lot smaller, but i wnat to keed the width to keep the ridgidity.
I only use profiled rail, so no round or supported round rail.
If you have a more details specification, email it over to me and i can work out what you need.
