SELECTION OF MATERIALS FOR LUBRICATED JOURNAL BEARINGS

For the selection of materials for lubricated journal bearings, which occasionally have to operate under conditions of solid-to-solid contact, a number of selection criteria are proposed. Typical tribological criteria are: the coefficient of friction, the contact parameter and the wear rate, as measured under conditions of boundary lubrication and in the presence of an abrasive. A method for ranking materials with respect to these criteria is recommended. An example of the application of the method involving the ranking of five bearing alloys is presented.
