Precision Granite Air Bearing Block for Ultra-Precision Motion Systems
When your motion system pushes toward nanometer-level resolution, the foundation matters as much as the sensor or the linear motor. Every fraction of micron in vibration, thermal drift, or geometric deviation shows up directly in your measurement repeatability and process yield. This precision granite air bearing block was engineered specifically for those unforgiving environments.

- • Zero Friction, Zero Wear: Air bearing technology completely eliminates mechanical contact between moving parts. This means no lubrication, no particulate generation, and infinite life—critical for Class 1 cleanroom semiconductor equipment.
- • Unmatched Thermal Stability: With a near-zero coefficient of thermal expansion, this block won't warp or shift as temperatures fluctuate. Your measurements stay true from warm-up to steady-state.
- • Superior Vibration Damping: The granular structure of high-density granite naturally absorbs micro-vibrations up to 10x faster than steel. This results in faster settling times and higher bandwidth for your control loops.
- • Monolithic Structural Integrity: Machined from a single block, there are no glued joints or composite layers that can delaminate, creep, or drift over years of continuous use.
- • Fully Customizable Integration: Whether you need specific tapped hole patterns, custom air plenum geometry, or integrated cooling channels, we can adapt the design to your exact assembly requirements.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q: Can this granite air bearing block be customized for my specific stage design?
A: Absolutely. We provide full design-for-manufacturing (DFM) support. Whether you need specific tapped hole locations, custom air plenum shapes, or non-standard dimensions, our engineering team can adapt the design to integrate seamlessly with your existing guideways and linear motors.
A: We exclusively use premium high-density black granite (≈3100 kg/m³). This material offers superior stiffness, lower porosity, and better long-term dimensional stability than standard granite or marble. We provide material certification with every shipment.
A: For standard air bearing applications, we typically achieve flatness and parallelism within 1 µm / 25 mm. For ultra-precision requirements, we can hold sub-micron tolerances (down to 0.5 µm / 25 mm) using our in-house nanotechnology-grade grinding and lapping processes.
A: Yes. Every precision granite component ships with a full dimensional inspection report. For air bearing surfaces, we can provide flatness maps and surface roughness data, calibrated against NIST-traceable standards.
