Needle bearings are for low load applications, ball bearings and bushings are for heavier loading. Not only will needle bearings get flat spots, the cages may crack from the constant shock loading.

In Packards, caged needle bearings are used in king pins, lower outer pins, clutch linkage and similar applications. Uncaged needle bearings were used on cam followers and often wore out prematurely
