Abstract

A novel profiled flat pad aerostatic bearing design is presented that takes advantage of a manufacturing technique made possible by the Zeeko IRP-200 polishing machine. The performance of this bearing is analyzed using the Finite Element Method and compared with the traditional orifice bearing. The comparison shows that the load carrying capacity is increased by 2.5 times, the maximum stiffness is 11 to 35 times of the orifice aerostatic bearing, the flow doesn't increase considerably, and when the depth of surface features increases the flow has a tendency to saturate.
