Cylindrical roller bearings mounted to a continuous casting machine were only lasting 1-2 months prior to failure at a major steelmaking plant in Europe. To remedy the situation, the facility invited NSK's team of experts to review the application and operating conditions, a process that ultimately led to the adoption of NSK's sealed spherical roller bearings. The result: annual savings of €14,850 in downtime and maintenance costs.
The machine in question produces I-section beams using a series of rolls to maintain pressure on the profile as the molten steel solidifies. Shaft-mounted bearings support each set of rolls.
