Four-row cylindrical roller bearings are available in many designs dictated by the application o r by maintenance considerations. these bearing are commonly used in Rolling mill. The various designs differ basically in the number of inner and outer rings as well as in the number of loose o r integral flanges on the outer ring. There are also differences in cage design and in the number of rollers per cage pocket.

For bearing arrangements (up to 8,5 m/s rolling speed) where the bearings are mounted with a loose rather than an interference fit on the roll neck, in o rder, fo r example, to enable rapid roll replacement in the chocks, Four-row cylindrical roller bearings are supplied in special designs. To largely compensate fo r the disadvantages of the loose fit (the inner rings wander on the seat which can damage both bearing and seat), these bearings have a helical groove in the bo re and/o r lubrication grooves in the side faces of the bearing rings .These grooves enable the mating surfaces to be efficiently lubricated.
