Cylindrical Roller Bearings
Single row cylindrical roller bearings are units with solid inner ring, outer ring, cylindrical roller and/or cage assemblies. Inner ring and outer rings are designed with one side rigid rib, both sides rigid ribs or no rigid rigs. The cage prevents rollers to rub each other during rolling. Cage type cylindrical roller bearings are very rigid, support high load on high speed compared to full compliment bearing. Bearings with suffix E have higher load carrying capacity. Cylindrical roller bearings are classified into following types depending on passion of ribs.
Non locating Bearings: NU and N type cylindrical roller bearings are non locating bearings and can support only radial load. Semi locating Bearings: NJ and NF type cylindrical roller bearings are semi locating bearing and they can support one direction axial load along with high radial load. Opposite direction they act as non locating bearing. Locating Bearings: NUP and NH (NJ with HJ ring) type cylindrical roller bearings are locating bearings and support axial load in both the direction along with high radial load. Races and Rollers: Inner, outer races and rollers are manufactured of high quality bearing steel (SAE 52100) for optimum performance.
