Here we discuss the fundamentals of air bearings used for the ultra-precision, very high accuracy motion, oil-less operations and the applications where air bearings should be used and not to be used. The concept behind a bearing is very simple: Things roll better than they slide. – Bearings mounted in the back-to-back mode use axial thermal growth to cancel radial thermal growth and thus remain thermally stable at high speeds – Bearings mounted in the face-to-face mode are more tolerant of misalignments, but axial thermal growth effectively adds to radial thermal growth and causes the bearings It varies from 00 to 900.
