T E C H N I C A L I N F O R M AT I O N The following chapters only show a small portion of the wide field of applications for ball screws. In order to meet all the technical and commercial demands for such a wide variety of different tasks, a deep understanding of the technology of ball screws is absolutely necessary. We have collected extensive information about ball screws in this section of this catalogue and hope that you will find it useful. Please be aware that although we edited this information as carefully as possible, we cannot be held responsible for missing or incorrect...

PRECISION (LEAD ERROR, FRICTION TORQUE, CRITICAL TOLERANCES) Under the headline „precision" DIN / ISO standards are explained as they apply to ball screws, how accuracies are defined, and the acceptance or specification criteria derived from these standards. Lead accuracy Friction torque Roundness, concentricity and squareness of relevant surfaces In general, all acceptance criteria should be reviewed and agreed upon between Steinmeyer and our customer. This is especially relevant for those applications where special demands are required, for example a lead accuracy of class 5 but friction...

Positioning ball screws Transport ball screws The DIN standard differentiates between positioning ball screws and transport ball screws. Positioning ball screws are normally used in high-precision applications (like machine tool) and are usually equipped with a ground ball thread. Transport ball screws are predominantly used for travelling and moving applications. Typical applications are axes for handling systems. Ball thread of such screws is usually rolled or whirled. Per DIN standard the tolerance classes for positioning ball screws are described as "P" while the transport ball screws...

Lead error fluctuation over entire travel Accuracy class [¹ n/a for rolled and whirled ball screws] TECHNICAL TIP The fluctuation of the lead error is defined by two lines parallel to the line representing the average lead error, which include the entire lead error graph. The lead error fluctuation is applicable to precision ground positioning screws in accuracy classes 0 - 5 only. It does not apply to general purpose screws which are typically either rolled or whirled in classes 5 - 10. Lead error fluctuation per 300 mm The variation over 300 mm is the most common definition. However it is...
