Ball screw drives convert rotary motion into precise linear motion or vice-versa. They are often used as a drive element. Positioning accuracy is critical when using ball screw drives. One way to increase the positioning accuracy of a ball screw drive is to reduce the play between the spindle and nut with a preload. However, since this preload also changes the ease of movement of the system, there are ball screw drives with adjustable preload. The system can be preloaded to such an extent that the permissible axial play between the ball nut and the threaded spindle is achieved without overly limiting the free movement. Preloading can achieve positional accuracy within a few micrometers. In this article, you will learn how this works and what accuracy classes there are.

Technical plastics are an indispensable part of modern industry. In custom machine construction in particular, they find a wide range of applications because they have a high degree of flexibility and formability. It is important to know what properties plastics must have in components and standard parts in custom machine construction. This article describes the most important applications for plastics in mechanical engineering.
