Description:

Abstract:

An improved hydrostatic way-bearing construction is disclosed utilizing hydraulic preloading of opposed way bearing surfaces between relatively slidable machine tool members. Said construction comprises preload gibs having hydrostatic bearing surfaces, preloading being accomplished by a plurality of longitudinally spaced hydraulic actuators, some recessed within the hold down cleats of the supported member and others recessed within one of the preload gibs. All of the bearing surfaces are completely enclosed by seals and exhaust oil therefrom is scavenged by means of a suction pump.
