Circular Flat Air Bearings LRAP400 / 610-22457
Able to support over 500 pounds of load force, this 4 inch diameter air bearing will move large stage assemblies without friction. Remarkably, this bearing is supported by a cushion of air only 5 microns in thickness and has the same stiffness as a normally loaded solid piece of steel 2 inches in diameter, 7 inches long.
