Roll bearings and productive papermaking

There was a time when paper machine roll bearings were essentially unprotected and short lived. A continuous supply of grease, with water washout properties, was routinely recommended to purge moisture, dirt, and other contaminants from the bearing locations. To enhance the reliability of the papermaking process, a workable method must be found that will keep machine roll bearings and their lubricants contaminant-free and prevent the contamination from entering the system in the first place. Over-greasing of bearings is one of the most common reasons for bearing failure in the paper industry; bearing isolators practically eliminate this chronic problem.
