NA 4900 | XIC | Machined Type With IR | NA Series

NA 4910

The NA 4910 is a single‑row, machined‑ring needle roller bearing with inner ring and flanged outer ring. It offers high radial load capacity and excellent stiffness while maintaining a low cross‑sectional height — making it suitable for compact mechanical assemblies, gearboxes, pumps, alternators, and other machinery where radial space is limited but load demands are high. The design allows for smooth, precise rotation, good load distribution, and easy relubrication thanks to lubrication groove/holes in the outer ring. Its robust construction ensures reliability and long service life under continuous or heavy‑duty operation.

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.
