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.
Hydrostatic Bearing Grinding Mills. Ball Mill Bearing Design Hydrostatic Bearing Grinding Mills Components and mode of functioning: The hydrostatic sliding shoe bearing arrangement works on the principle of a plain bearing. During operation there is no metallic contact between the contact surfaces.

Hydrostatic bearings and hydrodynamic bearings are fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements. Although they may be similar in appearance, hydrostatic and hydrodynamic bearings are different in operation from plain bearings.

Hydrostatic Bearing Upgrade; Hydrostatic Bearing Upgrade. The Outotec hydrostatic bearing (HSB) upgrade is a retrofit solution for grinding mills. Existing bronze bearing pads are replaced with pads made from an advanced compound that significantly improves the maintainability, reliability, and longevity of both radial and axial pads. BENEFITS
The new Outotec® MH Series Grinding Mill range offers flexible and easily deployable solutions that are costeffective and easy to operate and maintain. Along with the new mill offering, Outotec is also introducing the Outotec® Polymer Hydrostatic Shoe Bearing (HSB) system, designed to maximize grinding mill availability and simplify maintenance.
bearings are still running decades and decades after they were first built. The principal problem with hydrodynamic bearings, however, is that the thickness of the hydrodynamic layer, and hence the accuracy of the bearing, depends on speed. Perhaps this is what led to the development of externally pressurized, or hydrostatic bearings ...
Capable of handling the world''s heaviest loads in the harshest conditions, SKF hydrostatic shoe bearings operate with a supply of pressurized oil to support the massive loads. Designed to work with grinding mills, kilns and cement mills, these unique bearings offer: High carrying capacity; Unlimited support diameters; Virtually no friction or wear

Bearings that interest us are in 3 categories: Hydrodynamic, Hydrostatic, and Roller. Hydrodynamic and the hydrostatic make use of a phenomenon called the Wedge Effect. This wedge effect is a selfgenerated pressure that is developed when a film of oil between a moving shaft and a collar or sleeve is forced through a wedge shaped passage.
