Troubleshooting Paper Machine Problems Through Thermal Imaging

Bearing repair is not a new concept, nor has it changed a great deal over the years — and that's good news. Repairing damaged bearings is a precise science that has been fine-tuned over time through careful and gradual enhancements to provide superior results.

There is another, often overlooked, type of preventive maintenance inspection which can not be scheduled at regular intervals.

A long time ago, I discovered that most maintenance people like gadgets and smart methods, especially from within their fields. I must include myself in this group, and have learned to use the knowledge of a variety of maintenance methods to keep up my own enthusiasm while generating interest and commitment for implementing better preventive and corrective maintenance practices. Most of these methods are old, but they are very new to many, especially to people who are just entering the area of maintenance.
