Ball Screw

Ball screws are a drive element that converts a rotary motion into a linear feed motion via a screw thread. In this process, balls serve as a bearing element between the screw thread and the threaded nut. In this way, a backlash-free bearing arrangement with very low friction and associated high efficiency can be achieved. As a result of the lower temperature rise that occurs during operation compared to a trapezoidal screw drive, a ball screw drive is also suitable for continuous operation.

Rolled lead screws, ground lead screws or whirled lead screws are used as screw threads.

This type of linear guide offers maximum precision and load capacity with unsurpassed running behavior. It is therefore generally used for measuring equipment, in optical instruments, in medical technology and in precision machining.
