THRUST AIR Bearings & bushings

High-Load Capacity with Three-Way Frictionless Thrust Motion

OAV Thrust Air Bearings and Bushings are engineered to support high axial loads while delivering true non-contact, frictionless motion. Utilizing porous GraphAir™ film technology, these bearings create a uniform pressurized air layer that eliminates mechanical contact, wear, and heat generation.

Designed for precision applications, thrust air bearings provide exceptional stiffness, load capacity, and stability under demanding conditions. The air film is evenly distributed across the bearing surface, maintaining a consistent gap that ensures accurate positioning and smooth motion even at high speeds.

Manufactured from aerospace-grade materials, OAV thrust air bearings operate without lubrication, reducing contamination and maintenance requirements. Their robust design makes them ideal for applications requiring high load support, precision alignment, and long-term reliability.

Key Benefits

• High axial load capacity with exceptional stiffness
• Three-way frictionless working surfaces
• Uniform air film distribution for stable load support
• No lubrication required (cleanroom compatible)
• Eliminates heat generation and mechanical degradation
• Long service life with minimal maintenance

Common Applications

• Semiconductor manufacturing equipment
• Precision machining and grinding systems
• Rotary tables and thrust load positioning systems
• Optical alignment and metrology equipment
• High-speed automation and motion platforms
• Cleanroom and contamination-sensitive environments
