Controlled porosity alumina structures for ultra-precision hydrostatic journal bearings [PDF]

open access: yes, 2010
A series of fine-grade alumina powders has been used in combination with maize starch granules to produce porous structures for porous hydrostatic journal- bearing applications. A comprehensive series of tests was conducted to characterize porosity in

Thermoelastohydrodynamic Behavior of Hydrostatic Thrust Bearings

open access: yesHydraulics & Pneumatics, 1990
The thermoelastic behavior of hydrostatic thrust bearings is analyzed numerically. Mineral oils, HWCF, seawater, and tap water are studied as working fluids. The physical properties of these fluids are expressed as a function of temperature and pressure. The heat transfer and thermoelastic distortion of the bearings are considered.

Experimental equipment for measuring physical properties of the annular hydrostatic thrust bearing

open access: yesEPJ Web of Conferences, 2014
The hydraulic circuit, through which the mineral oil is brought, is an important part of hydrostatic bearings. The annular hydrostatic thrust bearing consists of two sliding plates divided by a layer of mineral oil.

Kugel ball nature: hydrodynamics-mathematics-design

open access: yesApplications in Engineering Science, 2022
The Kugel fountain, where a sphere sits in a fitted socket fed by a thin film of pressurized water flowing between the sphere and the socket, was treated as a bearing without referring to any mathematical or practical evidence that can support this idea.

Development of rotary table grinding machine for large diameter Si wafers (2nd report: Performance investigation of wheel spindle designed to govern infeed motion)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Si wafer diameter tends to be increased from 300 mm to 450 mm in order to increase semiconductor device productivity. To this end, the authors developed a rotary grinding machine with high stiffness, equipped with water hydrostatic bearings.

An isoviscous, isothermal model investigating the influence of hydrostatic recesses on a spring-supported tilting pad thrust bearing [PDF]

open access: yes, 2012
Tilting-pad hydrodynamic thrust bearings are used in hydroelectric power stations around the world, reliably supporting turbines weighing hundreds of tonnes, over decades of service. Newer designs incorporate hydrostatic recesses machined into the sector-
