EPOXY BONDED 
air Bearings

Epoxy Bonded Porous Graphite Air Bearings

Epoxy bonded GraphAir™ bearings use a precision-applied epoxy layer to bond the bearing surface to its supporting structure. This design improves stiffness, increases accuracy, and reduces friction while maintaining a compact, low-profile form.

The epoxy layer acts as a damping interface, enhancing vibration resistance and enabling stable, near-frictionless motion in demanding environments. These air bearings are engineered for high precision applications requiring long life, thermal stability, and consistent performance under load.

Key Benefits

  • Integrated low-profile design for compact systems

  • High stiffness with excellent load distribution

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

  • Uniform air film for stable, repeatable positioning

  • Vibration damping through epoxy bonded interface

  • Cleanroom compatible with no lubrication required

Common Applications

  • Precision stages and compact linear motion systems

  • Semiconductor manufacturing and inspection equipment

  • Optical alignment and metrology platforms

  • High-speed automation and positioning systems

  • Precision machining and grinding applications

  • Cleanroom and contamination-sensitive environments

Epoxy Bonded Air Bearings

Ultra-Precision Linear Motion

GraphAir™ bearing technology creates a uniform pressurized air film, enabling frictionless, non-contact motion with exceptional straightness, stiffness, and repeatability across long travel distances.
