X-Spin Rotary Air Bearings

  • NEW patent pending OAV X-Spin Roller Air Bearing is here to replace conventional bearings with improvements & efficiency that is unmatched.
  • Available in 13mm, 40mm & 75mm inside diameter versions.
  • Incredible accuracy with a total indicated runout, TIR of 0.025um.
  • The OAV Air Bearings surface design equally distributes the air and preloads it over an entire surface area.
  • This results in outstanding stiffness as well as maximized performance levels.

Product Description

The Outer Spin Rotary Air Bearing provides the ability to spin outer rings with an incredible accuracy of TIR± 1 millionths inches (.025 microns) while maintaining zero friction and contact, zero maintenance, no generation of thermal energy at high speeds, and a limitless operating life. This ultra-precise, hard-installable innovation is here to replace conventional bearings with unmatched improvements and efficiency. OAV Air Bearings offers products that have significantly higher levels of stiffness with superb geometric performance.

The OAV External Spin Rotary Air Bearing preloads both the horizontal and vertical surface with an opposing thin film of pressure, maintaining the perfect gap and optimal levels of tolerance.
