NA 4903 | XIC | Machined Type With IR | NA Series

NA 6903

The NA 6903 is a needle roller bearing with a machined inner ring and outer ring flanges, built to deliver high radial load capacity while maintaining a relatively low cross‑sectional height. Its dense arrangement of small‑diameter rollers ensures firm load distribution and smooth, dependable rotation — ideal for gearboxes, pumps, motors, and other industrial machinery where robust performance and compact design are required. Constructed from bearing-grade steel, NA 6903 offers good durability, low friction, and long service life under continuous or heavy-duty conditions.

NA 5912

The NA 5912 is a machined‑ring needle roller bearing with inner ring, designed to provide high radial load capacity while keeping a relatively low cross‑section. Its design — featuring many fine rollers running on a hardened inner ring — offers excellent rigidity, smooth rotation, and reliable performance under continuous or demanding operating conditions. This bearing is ideal for industrial gearboxes, pumps, conveyors, and other mechanical assemblies where compactness, high load‑carrying capability, and long service life are required.
