Rolling mill bearing belongs to one of the mechanical bearing, below is the common rolling mill bearing:

Self-aligning roller bearings, early rolling mill bearing in rolling mill in configuration forms and now it is different, when mainly USES the two sets of spherical roller bearing paratactic installed on the same roller neck. This configuration types satisfy basically when production conditions, rolling speed can reach 600rpm. But as the speed increase, its faults are becoming more and more serious: bearing life is short, consumption, low, the precision roller neck badly worn, rolling the roller to move large etc, so there for early these defects, SKF TIMKEN, NTN, etc, the import bearings company also developed the new type of bearing high.
