Air Bearing Guides Air bearings can be run on different types of guide material. Common guide surfaces include granite, hard-coated aluminum, ceramics, glass, stainless steel, and chromed steel. Guide Surface Considerations Surface finish, local flatness issues and possibly even holes in the counter surface need to be taken into consideration.
The subject publications incorporate the tribological aspects like chemistry, friction and design not dealt with in this review, while their decision application includes material design, medical, lubricant additives design and machinery. This current review focuses on publications leading to maintenance application.
lubricant selected for the application cannot support the machine’s demands. Many criteria must be considered when selecting a lubricant for a set of machines or machine components. Lubricant chemistry has an influence on the final decision. The basestock (synthetic or mineral) and the additive systems in use (EP, AW, R&O) exert tremen-

one through the bearing’s axis, those lines would all meet at a common point (fig. 3). Those same lines along the surfaces of ball or cylindrical roller bearings are parallel. The advantage of this design is that the tapered rollers have a positive alignment with the shaft. That is, each roller will align itself
