Hybrid deep groove ball bearings in spreader rolls

Paper machines generally run 24 hours a day, more than 350 days a year. If the machine experiences unplanned downtime, this incurs additional costs of the order of several thousand euros per hour. All the components must be highly reliable. A long operating life is also required. For conventional deep groove ball bearings in spreader rolls, a fatigue life of more than 100 000 hours has been calculated. In practice, however, the service life actually achieved is often significantly less than 20 000 hours.
