Granite linear guides and air-bearing guideways provide frictionless motion for high-speed automation. They offer higher stiffness and damping properties than steel, making them essential for advanced precision measuring tools and semiconductor equipment.
How do granite air bearings improve motion control?
Granite air bearings use a thin film of compressed air to float the moving part. This eliminates mechanical friction and wear, allowing granite mechanical components to achieve nanometer-level positioning accuracy essential for semiconductor manufacturing.

Why is vibration damping critical for linear guides?
High-speed machines generate vibrations that ruin precision. Granite has excellent vibration damping capabilities (15x higher than steel). This ensures that precision measuring equipment remains stable even during rapid acceleration and deceleration.
