How to Build a Better Linear Drive System

May 16, 2017
Synopsis: This paper examines how rack and pinion drives compare to linear motors and ball screws. Four key areas are examined: Linear Motion, Ball Screws, Backlash and Electronic Pre-Loading and Inertia. Sponsored by Wittenstein
With advances in precision manufacturing and the advent of electronic preloading, the accuracy and performance of rack-and-pinion drives can match or exceed that offered by competing hardware – often with better durability, efficiency and economics. This paper outlines four key areas for comparing rack-and-pinion drives to linear motors and ball screws.
