NA 6903 | XIC | Machined Type With IR | NA Series

NA 6904

The NA 6904 is a needle roller bearing with a machined inner ring, built to offer high radial load capacity while fitting into limited radial space. Thanks to its design — including a full set of small‑diameter rollers guided by flanges on the outer ring — it delivers dependable, smooth rotational performance under heavy and continuous loads, making it suitable for gearboxes, pumps, motors, and various industrial or mechanical applications. Constructed from quality bearing steel, the NA 6904 offers robustness, good wear resistance, and long service life when properly lubricated.

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.
