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

Lubrication Basi

It’s a vicious cycle, and the way we prevent this from occurring is by creating a lubrication film. Two of the preferred and most common types of fluid related lubricant films are hydrodynamic and elastohydrodynamic. Hydrodynamic films are present between sliding contacts. The most common example would be a journal bearing.

Lubricant selection: Function and composition - ST

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-
