Temperature CONTROLLED THRUST AIR BUSHING

Thermally Stable Air Bearings for High-Temperature Precision Applications

OAV temperature controlled thrust air bushings are engineered for high-speed applications operating in elevated or fluctuating temperature environments. Utilizing porous graphite air bearing technology, these systems maintain a stable, uniform air film that enables frictionless, non-contact motion—even under thermal stress where conventional bearings lose accuracy and reliability.

​

By actively managing thermal conditions, these air bushings preserve critical tolerances and minimize distortion caused by heat expansion. The result is consistent stiffness, precise load support, and stable positioning performance across a wide temperature range. Opposing air films preload both axial surfaces, maintaining a controlled gap for ultra-precise thrust motion.

Key Benefits

  • Maintains precision under elevated and fluctuating temperatures

  • Thermal stability minimizes expansion-induced errors

  • Consistent air film for stable axial load support

  • True non-contact motion (zero friction, zero wear)

  • High stiffness with controlled gap under thermal load

  • No lubrication required (cleanroom compatible)
