Air Bearing Spin Table with 6" Clear Aperture and Gas Port
ABTech developed this air bearing rotary stage for a customer specific application in lens alignment. This bearing has one independent gas port to direct a customer supplied gas up to a sample under test. The gas port jumps the air bearing gap which allows a friction free rotary union feature that has no affect on the accuracy of the air bearing.

Mult-Spin Unit with 3 Air Bearings in 1 Unit
ABTech inc worked with a leading precision bearing manufacturer to develop this multiple spin air bearing unit for torque testing. The inner bore is matched to the customer tooling to provide the inner friction free air bearing surface. The intermediate spin table and the outer spin table are completely separate air bearings and are floating independently of each other. The customer tooling locates on the two hardened stainless steel tapered sleeves located on the top of each air bearing.
