Abstract
An improved system for guiding one part relative another in an accurately defined path, both planar and linear, is disclosed. The improved system eliminates friction associated with heretofore moving parts, is characterized by simplicity and cost effectivness, and comprises a first part having a primary reference surface prepared to close tolerances and accurately defining a predetermined path and an opposed parallel secondary surface, and a second part designed for guidance by the primary surface. A fixed air pad is adjustably mounted on the second part adjacent the primary surface. A second air pad is resiliently mounted on the second part adjacent the opposed secondary surface. The resilient mounting includes a bellows. Fluid under pressure is admitted to both air pads, directly to the first and indirectly via the bellows to the second. Preferably, the fluid is compressed air.
