NF style single row cylindrical roller bearings are designed to support heavy loads and are some of the most common bearings used among the world. These bearings consist of an outer race, brass or steel cage, a complement of rollers and usually an inner race.

Single row cylindrical roller bearings NF-type outer ring has a rib on one side and a rib on both sides of the inner ring. They can withstand a certain amount of one-way axial load. Therefore, this type of structure is suitable for using as a unidirectional axially oriented bearing.

In addition, the code K refers to tapered bore, the E refers to the polymer cage, the M refers to brass cage, while the code S is pressed steel cage.

Application

The cylindrical roller bearings are widely used in ement making equipment such as crushers; vertical, ball and rolling mills; conveyor drives; gear reducers, spherical pillow blocks; trunnions and rotary kilns.Power generation equipment such as pulverizers, gearboxes, and gear drives.Oilfield equipment such as mud pumps, drawworks, swivels, block hooks, crown blocks, traveling blocks and top drives.
