In the field of automobile engineering, engine bearings have demanded a great deal of attention. The trend of automobile engine development has been towards higher horsepower, higher speeds, greater efficiencies, and smoother operation. This has, in general, meant higher bearing loads and higher operating temperatures. Added to this has been the objective of lifting engine bearings from the classification of |service replacement parts| to that of |parts lasting the life of the automobile.| How successful we have been in accomplishing this latter aim is shown by the following: In 1931 high-speed engine testing showed an average bearing life of about 250 hr. at 3200 rpm.; in 1941, making allowance for the higher test speeds prevailing, but making no allowance for the increase of 49 per cent in unit load which had occurred in the interval, tests averaged approximately 750 hr. before producing a comparable degree of fatigue failure in the bearings--an increase of roughly 200 per cent (see Fig. 1).
