Torque-resistant Ball Bushing

In contrast to a conventional linear ball bushing, which runs on a smooth shaft and thus has to be additionally secured against rotation, e.g. by using a second guide shaft, a torque ball bushing runs on a profiled grooved shaft with several guideways for the balls, a so-called torque shaft, and thus allows the design of a torsionally rigid linear guidance system with only one shaft.

Frequent use is, for example, as a drive shaft where the input or output must be displaced linearly without backlash, or when, for reasons of space, a classic circular guideway with two shafts and a eco rail guide cannot be used.
