Abstract : The high precision operation of machines and instruments at a very fast or very slow rate presents special lubrication problems because of the difficulty involved in maintaining a film of the lubricating agent between adjoining surfaces both during motion and standstill of the system. Hydrostating lubrication was found useful to assure operation of guides, providing continued liquid friction at all velocities and loads imposed on the machine. Theoretical and design problems of these lubrication systems with practically zero wear are presented. The maximum and minimum applied load and film thickness were determined without taking the geometry of the adjacent surfaces into account; therefore experimental correction factors can be introduced in the theoretically derived formulas.
