Vibrating screens are used for grading (i.e. separation of solid materials by grain size) of materials and other vibratory machinery such as road rollers and saw frames are among the machines subjected to the most severe stresses. 

The rolling bearings in the exciter units of these machines must support not only high loads and high speeds but also accelerations and centrifugal forces. Many of these applications involve adverse environmental conditions such as contamination and moisture.
