Bearings & Failure Modes

In many cases involving bearing selection during the initial design of a machine, obtaining a satisfactory rating life is the prime consideration. Once the loads and speeds have been determined, the question now becomes, “How many hours of rating life are needed for a well-designed machine?” Sometimes, this is spelled out either by specific industry standards or company policy based on the industry and customer expectations . The health of your bearings is critical to the health of your equipment and processes. With proper performance monitoring, imminent failures can be identified and corrected. Conversely, without a sound monitoring program in place and subsequent corrective actions not being taken when needed, a single bearing failure can result in full machine shutdown and countless hours of lost production.  Bearing monitoring is guided by three main human senses: sight, sound and touch. Basic monitoring has typically been conducted through elemental observations. Fortunately, there are a number of highly sensitive tools that can amplify these observations—making them more noticeable and recordable. They also include basic logic to assist with warning identification.
