Hydrostatic Bearings - an overview | ScienceDirect Topics

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.
