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
