The roller linear guide assembly is to place proper steel ball between slide and guide to make slide friction between slide and guide change into rolling with less static friction difference and good follow-up, that is the lagging interval between drive signal and mechanical action is very short, which is beneficial to improving response speed and sensitivity of NC system.
