Welcome to Nelson Air, a PI Company
Since 1984, Nelson Air has been designing and manufacturing precision air bearing components and air bearing positioning systems for science and industry.
Our products include flat pad, bushing, linear, rotary, spindle, spherical and planar air bearings and systems. We also specialize in delivering application-specific bearings and systems to meet your exact needs with the highest quality and service.
Nelson Air's air bearings outperform traditional mechanical bearings in a variety of high performance motion applications. Sometimes air bearings are the only solution to difficult motion problems.
Typical Applications for our Air Bearings
Air Bearings are extremely useful for 2 general categories of applications - frictionless motion and ultraprecision positioning. Frictionless motion applications take advantage of the totally noncontact nature of air bearings even when operating under heavy loads. Ultra-precision Positioning takes advantage of the extremely tight manufacturing tolerances required to make air bearings as well as their inherent error averaging to deliver the ultimate in ultra-high accuracy, straightness, flatness, pitch, roll, yaw, and runout.
