Abstract
A plurality of hydrostatic bearing pads are each integrally formed in a respective pin or journal member being used within a mechanical press machine. The hydrostatic bearing pads are supplied with pressurized fluid sufficient to create a combined hydrostatic and hydrodynamic effect between the opposed bearing surfaces of the pin and an associated bushing. The hydrostatic bearing pads are used in conjunction with rotational and oscillating bearings in which relatively little rotation, oscillation, or slow rotational speeds exist or where it is desired to minimize the effects of hydrodynamic action which creates bearing "lift off" on journal bearings. These types of bearings are particularly associated with crankshaft and connection journal bearings, connection pins, and pivot pins used by a rocker-type coupling assembly that couples a weight assembly to the press machine piston or slide assembly or drive assembly.
