Hey all,

I have a small pile of inexpensive THK MTF0802 ball screws. These guys have maybe 50 microns of axial play that I want to take out. Is it reasonable to use a coil spring to take it out? I need maybe 10-20 mm of travel, and my application requires relatively slow movement at a 100% duty cycle, and low loading... so relatively low forces across the board. I've never seen a ball screw preloaded with a coil spring... is this a reasonable thing to do?
