Circular Flat Air Bearings LRAP200 / 610-22453
The 2 inch diameter LRAP200 air bearing allows translational or rotational motion in a plane. The LRA series bearings can be combined in an assembly to constrain motion in various degrees. With a nominal air gap of 5 microns, the LRA series exhibit zero wear of the mating surfaces.
