NJ Type Cylindrical Roller Bearings With Steel Cage
Heavy-duty radial cylindrical roller bearings are designed to provide the highest possible radial capacity for a given cross section, and to perform under heavy radial loads. These bearings incorporate improved internal proportions developed through computer-assisted optimization studies to make maximum use of the total available cross-sectional area. Controlled contour rollers redistribute end-stress concentration and provide more uniform distribution of the applied load.
RIJ, RJ type cylindrical roller bearings with bore sizes from 100 mm (3.937 in.) up to 700 mm (27.5 in.) are shown, and even larger sizes can be provided on special order.
The RIJ, RJ type cylindrical roller bearings consists of an outer ring, a complement of controlled contour rollers, a cage and an inner ring. Bearing rings and rollers are manufactured from bearing quality steel.
Types RIJ and RJ have double-ribbed outer and single-ribbed inner rings and can support heavy radial loads, as well as light unidirectional thrust loads up to 10 percent of the radial load. The thrust load is transmitted between the diagonally opposed rib faces in a sliding rather than a rolling action. Thus, when limiting thrust conditions are approached, lubrication can become critical.
When thrust loads are very light, these RIJ, RJ type cylindrical roller bearings may be used in an opposed mounting to locate the shaft. In these cases, shaft endplay should be adjusted at time of assembly.
