Air Bearings are Critical in CMM and Metrology Applications
linear bearings, and axial and radial runout for rotary bearings, favor air bearings over mechanical ball and roller bearings in applications where the ultimate precision counts. Using high quality standard [...] determine size and position of the part being measured. Multi-axis air bearing positioning system with screw-driven Z-axis (Image: PI) In addition to CMMs, there are many types of metrology tools on the market [...] complex part geometry with extreme levels of precision. These parts can include turbine components, ball bearing raceways, engine bearings, camshafts, optics, and aerospace components. In these cases, PI
