NKIS 50 | Machined Type With IR | NKIS Series

NA 6902

The NA 6902 is a single‑row needle roller bearing with machined rings and an inner ring — engineered to deliver high radial load capacity while maintaining a low cross‑sectional height. Because of its dense arrangement of fine rollers and the flanged outer ring, it offers strong rigidity, smooth rotation, and reliable load distribution even in tight radial spaces. It’s commonly used in gearboxes, pumps, transmissions and other mechanical assemblies where compactness and high load capacity are required. The bearing is made from bearing‑grade steel and designed for durability, long service life, and efficient operation in demanding conditions.

NA 4908

The NA 4908 is a single‑row needle roller bearing with machined rings and an inner ring, featuring flanges on the outer ring for axial guidance. Its design allows for a large number of small-diameter rollers, which gives it high radial load capacity and excellent stiffness while keeping the sectional height low — ideal for compact mechanical assemblies, gearboxes, pumps, alternators, and other industrial applications where space is limited but load demands are high. Constructed from bearing‑grade steel with a steel cage, it provides smooth, dependable rotation with good wear resistance and long service life under continuous or heavy‑duty use.
