OAV ® X-Roller Air Bearing NEW Patent Pending OAV ® External Spin Roller Air Bearing will replace your conventional bearing..
OAV ® X-Roller Air Bearing
The Outer Spin Rotary Air Bearing is yet another significant advancement produced by OAV Air Bearings. This innovative product is hard-installable and ultra-precise with a fixed location, here to replace your conventional bearing, supply airlines through the shaft or inner ring. The result of this product, No friction non- contact, no maintenance requirement, Ultra High Speed, limitless operating life, no heat generation at high speeds, and the ability to spin outer rings with an incredible accuracy of TIR± 1 millionths inches (.025 microns).
OAV Air Bearings offers products have significantly higher stiffness and excellent geometric performance. The OAV External Spin Rotary Air Bearing preloads both the horizontal and vertical surface with opposing thin film pressure, maintaining the perfect gap and ultimate tolerance. The OAV Air Bearings surface design equally distributes the air and preloads over an entire surface area, resulting in outstanding stiffness as well as maximized performance.

T.J. Davies' Retention Knobs
Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
