Air spindles utilize porous media technology to create a uniform cushion of air between the rotor and stator. This enables faster rotation speeds and high-precision rotary motion with less interruption or possible down time due to zero mechanical wear.
These air spindles deliver a degree of precision not achievable with conventional rolling element bearings. With only one moving part and zero contact, sub-micron synchronous error motion is standard and asynchronous error is almost entirely eliminated.
Air spindles are very low flow and do not consume nearly the amount of air competing orifice air bearing technologies use. If airflow is somehow disrupted, gradual depressurization of the porous media allows for a soft landing that won’t damage the bearing or rotor surfaces, unlike orifice air bearing spindles which often require a complete rebuild after such failures.
