  • Types of Lubrication - Boundary, Hydrostatic, and ...

    2020-7-31  Lubrication reduces friction between the moving surfaces or rolling pairs. Some of the various types include hydrodynamic, hydrostatic, boundary and extreme pressure lubrication. The lubricant also act as a coolant carrying heat away from the sliding surfaces so it is necessary for all the moving parts in machinery or engine operation.

  • 6 Hydrostatic Lubrication - ScienceDirect

    In hydrostatic lubrication the bearing surfaces are separated by a lubricating film of liquid or gas forced between the surfaces by an external pressure. The pressure is generated by an external pump instead of by viscous drag as is the case with hydrodynamic lubrication. As long as a continuous supply of pressurized lubricant is maintained, a ...

    2020-8-3  Hydrostatic lubrication. when the load increases up to such a level that the hydrodynamic lift caused by the lube oil is not sufficient to maintain the oil film between the moving parts hydrostatic lubrication is required. Instead of being self- generated lube oil pressure, it is supplied from an external source by oil under pressure from a pump.

    A hydrostatic slide bearing has an active lubrication circuit. High pressure pumps are creating an oil film between the shaft and the bearing surface before start up and during operation. URACA pumps are generating realiable the required oil pressure for these bearings.

  • Hydrostatic and Hydrodynamic Bearings Selection

    Hydrostatic BearingHydrodynamic BearingSpecificationsStandardsA hydrostatic bearing employs a positive pressure supply that maintains clearance between the rotating and stationary elements. With a hydrostatically-lubricated bearing, the lubrication is introduced under pressure between the moving surfaces. Hydrostatic bearing spindles feature high stiffness and long bearing life, and are often used for fine machining and finishing. Because hydrostatic lubrication does not depend on relative motion to maintain the lubrication film, it can accommodate heav...
