The Ball Screws by Dr. Tretter ensure, for example, in machine tools or all-electric injection molding machines for high speeds. The linear actuators are also mechanically very stiff, so vibrations are prevented. Thus, they continue to provide high positioning. They are offered in a ground finish in accuracy classes C0 to C5. Feinstgeschälte spindles are in the classes C5 to C7, precision-rolled screws in C7 to C8 and normal rolled spindles in class C10.
The drive units are supplied with preloaded nut on request. Thus, the ball screws move without axial play. This increases the positioning accuracy and ensures a smoother run. Dimensions and mounting dimensions of ball screws are also available in accordance with the DIN 69051-5 standard. Thus, they are compatible with other series. The components are available in lengths up to 4000 mm and in different grades. The program includes more than 500 variants. On request, the ends are machined according to customer drawings.
