Application Load and Life Factors

The Lundberg-Palmgren theory and the standard load and fatigue life calculations that

resulted [1-5] are only the first step toward determining the bearing fatigue lives in applica-

tions. Use of the standard methods should be limited to those applications in which the

internal geometries and rolling component materials of the bearings employed conform to the

standard specifications, and the operating conditions are bounded as follows:

. The bearing outer ring is mounted and properly supported in a rigid housing.
