Bearings – GM Hydro

HYDROSTATIC BEARINGS In general hydrostatic bearings are used mostly when the relative velocity between fixed and movable parts is low, as for example in telescopes. High relative speeds imply more entrainment of the oil or of any fluid passing through the fixed and the rotating parts, increasing in this way the power employed.
