Aerostatic bearing base - comprises alternating layers of ceramic plates and film with breaks in film to give air feed and form air jets

摘要

The basic body of a linear guide for an aerostatic bearing and the like, with connections for compressed air feed and distribution and air jets, composed of alternating layers of ceramic plates (1), film (2) and a ceramic closure (3). Breaks are formed in the film layers (2) for the air feed to give the contours for the air jets. An air distribution channel (4) is in each ceramic plate (1). ADVANTAGE - The assembly is a precision unit, with high resistance to wear, is free of magnetism and is unaffected by temp. The assembly is simple to produce.
