  • Optimum design of externally pressurized air bearing

    2009-8-1 · It is shown that the GA for air bearing design can be effectively dealt with by using the CLOMP computing (parallel efficiency of 96.2–98.8%) as well as the SMP (93.1–96.9%) in the studied cases. It is noted that the eight-thread curve in Fig. 8 shows a lower speedup at grid-size of 150 than that of 100.

  • AIR BEARING APPLICATION AND DESIGN GUIDE

    The design of the air bearing is such that, although the air constantly escapes from the bearing gap, the pressure between the faces of the bearing is enough to support the working loads [5]. Thus, there is a differentiation that has to be made between hydro-dynamical bearings, which establish the air cushion through their movement, and ...

  • Optimum Design for CMM by Robust Design | Open

    2016-12-16 · A 6” diameter air bearing running at 60psi has a stiffness of 2,000,000 lb/in with a load of 1,000 lb. This corresponds to less than one half a millionth of an inch deflection per pound of force. As an air bearing deflects, the air gap is reduced and in turn the stiffness is increased. This high
