What is an Air Bearing?
An air bearing is a non-contacting system where a gas film (typically air) acts as the lubricant that separates the two surfaces in relative motion.
- Greater precision and accuracy
- High speed operation up to 125,000 rpm
- Increased tool life and reduced wear
- Improved surface finish quality
- Long bearing lifespan
- Low thermal growth characteristics
- Minimal maintenance requirements
- Large load capacity
- Reduced vibration and noise
- Clean operation without contamination
