Typical bearings for BOF's and Converters cannot be replaced without removing the bull gear. Therefore if there is a sudden need for replacement due to unexpected failures large production losses can be incurred in the production process.  NSK's design structure with split bearings ensures that any bearing replacement is non-time consuming (work load reduced by approximately 35% against standard bearings) & helps reduce maintenance costs.
