Air Spindles

New Way® Air Spindles utilize Porous Media Technology™ to create a uniform cushion of air between the rotor and stator.

Unlike traditional spindle designs that require lubrication between moving parts such as belts and pulleys, air spindles rely on stiff air gaps to provide frictionless motion. Since the components are not in contact, wear is significantly reduced.

Porous material naturally restricts air flow through the spindles so there is no risk of pressure gradients between surfaces. If airflow is somehow disrupted, the surfaces gradually make contact instead of crashing together. In the event that there is damage to the surface of the spindle, the porous substrate still provides uniform airflow– reducing downtime for mechanical repairs.

With only one rotating element, New Way Air Spindles eliminate asynchronous error motion and reduce radial and axial error motion up to 0.1 μM. This allows for faster rotation speeds and high-precision rotary motion.

All air spindles come in a variety of sizes in both round or square stator configurations to accommodate an array of rotary applications. Contact New Way today to learn what we can do for you!
