Hydrostatic bearing systems

ZOLLERN offers hydrostatically mounted spindles, rotary tables, guides and bearing components for applications where freedom from wear, a high level of precision and running smoothness are required. For hydrostatic bearings, moving parts and housing are separated from each other by an oil film, independent of the load or sliding speed.

16 Hydroststic Bearing

16-9 Hydrostatic Bearings • Stiffness ¾Easily made many times greater than other components in the machine. ¾Dynamic stiffness is very high due to squeeze film damping. • Vibration and shock resistance ¾Excellent for liquid bearings. ¾Modest-to-poor for gas bearings.

Typical applications for hydrostatic and hydrodynamic bearings are machine tool spindles and slides; applications that require precise movement and high stiffness. Hydrostatic bearings and hydrodynamic bearings are both classified as types of fluid bearings.

Hydrostatic Slides

CBN Hydrostatic Grinding Spindle Systems This is an example of a hydrostatic spindle designed for high speed grinding with CBN grinding wheels. The small bearing diameter in combination with high surface speed allows the use of CBN wheels even for undercuts in a camshaft application.

Hydrostatic Bearings

Hydrostatic bearings are applied for demanding applications where conventional plain bearings and rolling bearings cannot meet the exacting demands of a grinding machine. However, hydrostatic bearing systems tend to be relatively expensive and will therefore be avoided if capital cost and machine simplicity are given priority.
