Rotary Air Bearings

Over the past 18 years, Nelson Air has developed an extensive catalog of rotary air bearings for diverse applications such as optical grinding, roundness checking, disk drive inspection, semiconductor processing, torque testing, and many others. Because of this, in addition to offering a line of standard air bearing tables, they can provide individually customized bearings for each application. When you call them with your rotary bearing application, they will quickly adapt one of their many existing designs to fit the exact requirements. And because they are small and flexible they can do this at a price and leadtime, which often beats their large competitors.
