Many of today’s manufacturers are faced with the increased demands of high-speed operations, coupled with extreme levels of precision. These unique requirements drive the need for machinery and tools which avoid friction to operate with high accuracy and reliability.

Air bearings provide an outstanding solution avoiding the traditional bearing-related problems of friction, wear and lubricants. One of the greatest benefits is that they provide new options for designers to push the envelope on precision, high speed, and high acceleration applications. Whether you’re an OEM or an Integrator, these porous media air bearings are not only a great technology but an outstanding product. Off-the-shelf or designed for your application, our years of experience with world beating precision design is here to help you change your paradigm.


At a glance

The advantages of designing with air bearings:

  • Zero friction and wear; better crash resistance and damping
  • Supports high speeds and acceleration
  • Ensures straighter motion (unlike rolling element bearings insensitive to surface finishes & guide irregularities)
  • Eliminates oil; positive air pressure self-cleaning in dusty environments
  • Performs a silent and smooth operation
  • Maintenance free
