The ball bushing is a technical sub-component that is used in combination with guide shafts either for longitudinal movements or for longitudinal and rotational movements in combination between an outer cylinder and a shaft. The ball bushings we offer are high-precision, torsion-free components that ensure consistently smooth longitudinal and rotational movements. Compared to the conventional ball bushing with rotary bearings, the rotary ball bushing has much more compact dimensions. Areas of application include machine tools, transportation equipment and the semiconductor industry.
