ABSTRACT
The loads applied to ball and roller bearings are transmitted through the rolling elements
from the inner ring to the outer ring or vice versa. The magnitude of the loading carried by the
individual ball or roller depends on the internal geometry of the bearing and on the type of
load applied to it. In addition to applied loading, rolling elements are subjected to inertial,
that is dynamic, loading due to speed effects. Most calculations of ball and roller bearing
performance, however, tend to consider only the applied loading when bearing operating
speeds are nominal. The objective of this chapter is to define the rolling element loading under
this condition, which might also be termed static loading.
