Four-row cylindrical roller bearings are suitable for very high radial loads due to the large number of rolling elements. They are used almost exclusively for back-up rolls in rolling mills.

​ Sealed four-row cylindrical roller bearings with extremely high load capacity have a long operating life and significantly extend inspection intervals even in highly contaminated conditions with insufficient opportunity for lubrication.

​ ​ Specially developed steel for high-load bearings with higher austenite content and special heat treatment. It has a very fine structure. This combination provides greater durability in dirty environments with insufficient lubrication. Super-TF steel provides a significantly longer service life under heavily contaminated operating conditions.

​ ​ Super-clean bearing steel developed specially for rolling mills. Advantageous under harsh operating conditions. This material provides higher reliability and longer operating life due to prevention of flaking stage and cracks caused by water infiltration.

​ These materials increase the bearing life several times, increase reliability in extremely demanding conditions and prevent unexpected accidents. They reduce maintenance costs to less than 50% of those with conventional bearings.
