premature bearing - failure. When a bearing does fail, it is important to determine the exact cause so apprcipriate adiusfments can be made. Examination of th6 failure mode ohn reveals the true cause of failure. ?his procedure is compli- cated by the fact that one failure mode may initiate another. For example, corrosion in

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

Each failure leaves its own special imprint on the bearing. Consequently, by examining a failed or damaged bearing, it is possible in the major - ity of cases to establish the root cause and define corrective actions to prevent a recur - rence. This publication is intended to provide a basic understanding of bearing failures and failure analy sis.
