Ultra-Large Split Bearings for BOF's & Converters

Spherical Roller Bearing, Ultra-Large, Split, Cut

Typical bearings for BOF's and Converters can't be replaced without the complex removal of the bull gear. Therefore large production losses can occur if there is a sudden need for replacement due to bearing failures.  NSK's design structure with split bearings ensures that any bearing replacement is not time consuming (work load reduced by approximately 35% against standard bearings) and facilitates a reductionin overall maintenance costs.
