Surface Roughness Measurement
Introduction Surface roughness measurement is the measurement of the small-scale variations in the height of a physical surface. This contrasts with larger-scale variations such as form and waviness which are typically part of the geometry of the surface. Surface roughness...
Meso Scale Air Journal Bearings
Meso scale air journal bearings are self-acting gas bearings used in compact, high-speed rotating systems such as micro motors, dental drills, laser scanners, hard disk drives and meso-scale turbomachinery. They use air as the lubricant, so they avoid oil leakage...
