Worldwide unique hydrostatic screw drives – all advantages at 1 glance

15 Advantages of lead screws compared to ball screws & roller bearings:

Wear-free, as there is no contact during operation
No loss of accuracy, even during long periods of operation under full load at maximum power.
Speed
Friction-free at low speeds
No reversal of the frictional force when changing the direction of rotation
Transmits the slightest rotary movements
No stick-slip effect even at low speeds
No fluctuations in the frictional torque due to ball circulation
Higher axial stiffness than ball screws
Much better damping: therefore better workpiece surface and tool life
No vibrations due to the ball circulation
Also suitable for high speeds and acceleration
low-cost alternative to the linear motor with higher accuracy, much lower
Heating
Much lower power loss and therefore no problems with chips on the permanent magnet
Many times lower cooling capacity than linear motors

Absorption of axial and radial forces and torques – Suitable for one-sided mounting of the threaded spindle
High-precision bearing of the screw drive
Double cones suspended between hydrostatic pockets for mounting in an “O arrangement”
Integrated volume control by pocket pressure only, only one hydraulic connection,
No additional electronic control required
All supply and discharge lines in the flange surface
Optional: Sealing to one side with sealing air/gap seal or sliding seal
Spindle ends are designed according to customer requirements
