Hi Open builds community I want to buy some ball screw but I have a doubt related with length of it including the end mounts. Should we take in consideration any extra length of the end mounts or if the length of the ball screw is per example : 400 mm is including the end mouths. I attached one of the images that I found : 400mm SFU1605 Ball Screw with BK12 BF12 Supports and 6.35x10mm Coupler for CNC Mechanical Parts from Tools, Industrial & Scientific on banggood.com In case someone order before please let me know. Thanks in advanced for all the answers.
Length is total length, end to end. Mounts plus ballnuts are standard sizes, I think ~100-110mm on 1605 and 60-70mm on 1204[/5]. The exact specs are available on manufacturer websites or just on Google Images, but you can definitely calculate your total travel distance ahead of ordering.
