Hertz contact stresses have a significant effect on bearing dynamic load capacity andL10 life. Shear stresses, which cause fatigue — a primary mode of failure of rolling elements — are proportional to the maximum Hertz pressure between the two bodies. Hertz contact, and the resulting deformation ...
The ABMA provides a means to modify the L10 rating with "adjustment" factors, known as [a.sub.1], [a.sub.2] and [a.sub.3] that are applied to the standard L10 value in order to determine an adjusted rating life ([L.sub.na]. The meaning of life: determining the lifespan of '...
