INFLUENCE OF SOLID PARTICLES IN OIL ON BABBIT, COPPER‐LEAD AND ALUMINIUM BEARINGS

In the last few years bearing research has begun to open a new field of information on the effects of solids in the oil to sleeve bearings. Actually, we are just beginning to evaluate some of the design conditions that have existed for years. It is, therefore, no longer sufficient merely to state that a given solid is good or bad for bearing lubrication—we also must know how good or how bad the effects of the solid will be on a certain bearing material. A series of tests on babbitt bearings was reported in June, 1952. Continued research on copper‐lead and aluminium operating with particles of molybdenum sulphide, rouge, and corundum has shown some very significant effects on the bearing's friction and load‐carrying capacity.
