Cylindrical Air Bearings LCAP150 / 630-43632

Number of Units:

The 1.5 inch inside diameter of the LCAP150 air bearing allows translational or rotational motion along a shaft. The LCA series bearings can be combined with other bearings in an assembly to constrain motion in various degrees. With a nominal air gap of 10 microns, the LCA series exhibit zero wear of the mating surfaces.
