Multi Row Cylindrical Roller Bearings have low cross section, high load carrying capacity and stiffness, and are particularly used for metal rolling equipment in mills, where the equipment has been scaled down and jet loads remain high.

NNU design
The bearings have two loose flange rings on the outer ring, a flangeless inner ring and four rows of rollers (fig) or eight rows of rollers (fig). The bearings are separable and enable a certain amount of axial displacement of the shaft relative to the housing in both directions to take place within the bearing.

Four row cylindrical roller bearings are being used in applications where a high loa capacity is required, chiefly in rolling mill stands, roller prsser and calendars. These bearings are designed for accepting high radial loads.

Six row cylindrical roller bearings are primaily used in small cold rolling mills for flat products where high forces and high speed occur.The bearings have an outer ring with two loose flangesand three loose guiding rings, between which the six roller rows are guided.
