  • How can I reduce or eliminate the backlash in a ball screw

    A ball nut with all the backlash removed is called preloaded. There are several ways to reduce or eliminate the backlash in a ball screw assembly At the factory level we can select ball sizes to minimize the backlash. This works well for small lead to diameter ratios like a 5x25mm. In some cases we can preload a ball nut in this way.
