Identification of mechanical problems of kiln support rollers
Any axial position changes bringing additional excessive stress to working components. This additional load is transferred from the shell through the shims and tires to support rollers and bearings and finally to concrete foundations. All parts of this chain of causes have to absorb excessive stress.

Diagnose bearing failures
Fatigue failure is related to the stress the bearing is subjected to over time. Fatigue failures in bearings typically originate sub-surface and eventually will propagate to the surface, and in time, will appear in what is referred to as a spall (see Figure 1). Fatigue failure is, in part, interrelated to the purity and the quality of the steel.
