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.
Features
- Unlimited theoretical life-time
- No vibrations from rolling elements
- No ball backlash through rolling element by reversal of rotation direction
- Frictionless by low speeds, in that way maximum positioning accuracy
- No stick-slip effect
- Economical alternative to linear motors
- Free of wear, no metal contact between the elements
- Speeds up to 90 m/min.
- Thermally stable, direct heat dissipation through lubricant
- Excellent suitable for rapid, oscillating movements
- Lead screws with external dimensions to customers' specifications can be supplied
