Advantages of Hydrostatic Over Rolling Bearings • Frictionless even at minute revolutions
• Transmits minute rotating motion
• No backlash when reversing direction
• Slip-stick effect is eliminated
• Wear is eliminated because there is no metal-to-metal contact during operation
• No loss of accuracy even after years of operation under full load
• No vibration as possible with bearings when ball direction is reversed
• Insensitive to dirt and contamination

Unique Technical Features • Handles axial, radial and torque forces
• Ideal for one-sided guidance of the leadscrew
• Highly precise bearing system for the leadscrew
• Integral volume regulation
• Only one hydraulic connection needed
• Input and drain lines are on the flange
• Optional seal on one side, or labyrinth air purge
• Adaptable to a machineâ€™s parameters:
• Axial, radial, and torque loads
• Maximum RPM
• Required stiffness
• Viscosity and temperature of hydraulic oil

Application: Hydrostatic Rotary Tables

The world's largest gear and profile grinding machines use hydrostatic bearings.

Hydrostatic Center Bearings

- Only one radial bearing
- Moment and axial forces are carried by an axial bearing
- Integrated clamping piston and rotating oil union for a hydraulic collet. The clamping piston is driven with hydrostatic oil and released with springs.
- Extremely minimal friction (results in minimal warming during continuous operation, and more of the motor drive force applied to the workpiece).

Hydrostatic Lathe Spindles

- Very low friction will heat the spindle only slightly. Nearly all motor power gets to the
workpiece. Heat that is generated is moved immediately out of the spindle area with the oil and cooled in the chiller.
- No vibration from roller bearings for extremely smooth operation.
- Excellent damping of vibration during grinding process, resulting in superior surface finish and workpiece accuracy. In addition, grinding wheels will stay sharp longer.

Hydrostatic Grinding Spindles with Integral Motors

- Very low friction will heat the spindle only slightly. Nearly all motor power gets to the
workpiece.
- Heat that is generated is moved immediately out of the spindle area with the oil and
cooled in the chiller.
- No vibration from roller bearings for extremely smooth operation.
- Excellent damping of vibration during grinding process, resulting in superior surface finish and workpiece accuracy. In addition, grinding wheels will stay sharp longer.
