Cylindrical air bearings often find use among frictionless rotating supports such as spindles.  Our expanding standard product line offers the UTT series universal turntables with nanometric rotational accuracy and remarkably high stiffness (see chart below).  Utilizing both cylindrical and thrust surfaces, these bearings provide load capacities up to 230 lbf.  Every UTT now features SAFELOCK(tm); a safe and effective way of restricting the rotor without loosing concentricity and parallelism with the stator.

The LCAP series air bearing bushing provide frictionless motion along linear shafting.  They can be used as a direct replacement for traditional mechanical rolling element or sleeve bushings.  All models are porous surface.

As part of our standard manufacturing process and immediately prior to shipment, each bearing is fully characterized for performance using our custom-designed testing equipment.  Automated data acquistion provides consistent, accurate and timely measurement of relevant parameters including: load capacity, flying height, flow rate, vacuum preload, temperature, humidity, inlet pressure, film pressure, barometric pressure, etc. Bearing surface sphericity can be measured using non-contact capacitance probe or laser based interferometric analysis.
