its hard for me to ask with my crappy english, the problem i had is, i doubt the longest ball screw end support, is it ok with 1 end fixed and 1 end simple? will it become a problem later? the ball screw length is 1577mm 20dia. 5mm pitch, is single nut fine for this?

How fast you want to spin the nut will tell you if the simple end will work. Look at the critical speed chart at www.nookind.com

Hi LCY

If the simple end has a bearing in the mount you will be fine like what you have
