Six-row cylindrical roller bearings

Six-row cylindrical roller bearings (fig 1) are used primarily for small cold rolling mills for flat products where the rolling forces are considerable at the same time as rolling speeds are high. The bearings have an outer ring with two loose flange rings and three loose guide rings, between which the six rows of rollers are radially guided. Three double pronged machine brass cages retain the rollers. The inner ring is without flanges so that limited axial displacements of the roll neck with respect to the chock can be accommodated within the bearing itself.
