Low-speed bearing monitoring – Challenges and Solutions, 2016 Pulping, Engineering, Environmental, Recycling, Sustainability (PEERS) Conference Proceedings

Reliability and performance of large size, low-speed bearings have a significant impact on mill output as they are used in critical applications such as twin roll presses, lime kilns, etc. A single unexpected failure can result in a production stoppage that costs tens to hundreds of thousands of dollars. Finding developing damage in these bearings through vibration measurement and analysis has always been a
focus in condition monitoring programs, but through the years results have been mixed. In this presentation, we will discuss the challenges of monitoring very low-speed bearings (20 RPM and below) as well as systems and techniques that have been found to be effective. Cases studies will be used to illustrate the results in real-life applications. One example will include root cause analysis of the bearing failure as well as subsequent solutions to increase reliability and in-service life.
