Hydrostatic lead screws

Hydrostatic lead screws permit the wear-free transmission of power from rotary movements to linear movements. Thanks to the no-play and hydrostatic pre-stressed nut, the hydrostatic lead screws are particularly suitable for highly dynamic, precise positioning functions in continuous non-stop operation.
