Double universal rolling mill with integral edging mills

The world's first double universal rolling mill with integral edging mills rolls two rails or girders simultaneously. Compared with a conventional installation, very much less space is required and all the problems of synchronizing the operation are eliminated. Total investment is also greatly reduced. SKF supplied four‐row cylindrical roller bearings for the horizontal rolls. Accurate axial location is provided by a double direction spherical roller thrust bearing. The vertical and edging rolls are fitted with SKF bearings as well.
