Frictionless Linear Motion with Air Bushings

OAV Air Bushings deliver ultra-precise, frictionless motion for linear air bushing applications using our advanced GraphAir™ film technology. Designed for precision shafts, they eliminate mechanical contact, reduce wear, and provide superior stability for high-performance motion systems.

Ideal for semiconductor manufacturing, metrology, aerospace, and automation, these bushings ensure consistent accuracy, long service life, and clean, maintenance-free operation.

Key Benefits

Ultra-precise linear motion for shaft-based applications
True non-contact operation (zero friction, zero wear)
High stiffness with stable load support
Uniform air film for smooth, vibration-free motion
Long service life with minimal maintenance
Cleanroom compatible with no lubrication required

Common Applications

Precision shaft guidance and linear motion systems
Semiconductor manufacturing and automation equipment
Aerospace and high-precision instrumentation
Optical alignment and metrology systems
High-speed automation and robotic motion
Cleanroom and contamination-sensitive environments
