The hydrostatic guides, rectangular guides and round guides from ZOLLERN impress with their damping and stiffness as well as the high traverse speeds that can be achieved. They are ideal for quick oscillating movements.
The freedom from friction at low speeds prevents slip stick and therefore allows maximum positioning accuracy.

Features, advantage Rectangular guides
Features
- Particularly well-suited for quick or evenly oscillating movements
- Friction-free at low speeds
- High damping due to the oil gap
- No vibrations from rolling elements
- Speeds up to 30 m/s
Advantages
- Calculative unlimited service life
- Very high positioning accuracy
- Thermally stable, heat removal directly via the lubricating oil
- No ball reversal jump due to rolling elements
- Only one oil connection to moving part necessary, therefore greater bearing stiffness compared to conventional restrictor systems
- Bearing characteristics independent of speed and inlet temperature - Throttling system used in every hydrostatic pocket
Features, advantages of round guides
Features
- Friction-free at low speeds
- High damping due to the oil gap
- No vibrations from rolling elements
- Speeds up to 30 m/s
Advantages
- Calculative unlimited service life
- Very high positioning accuracy
- Thermally stable, heat removal directly via the lubricating oil
- No ball reversal jump due to rolling elements
