  • What is back driving and why is it important

    2018/03/26 · This means lead screws often have lower efficiencies and as a result are less likely to back drive than ball screw assemblies. When does back driving matter In vertical applications most drive mechanisms—such as belts rack and pinion drives and linear motors—will let the load "crash" or fall if power is lost to the motor.
