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.

NA 4901

The NA 4901 is a single‑row needle roller bearing with machined rings and an inner ring, featuring outer ring flanges for guidance. It delivers high radial load capacity while keeping a low cross‑sectional profile — well suited for compact mechanical assemblies, small gearboxes, and lightweight industrial equipment where space is constrained but load demands exist. The needle‑roller configuration gives reliable, smooth rotation and good rigidity under load, and its steel construction ensures durability and a long service life.
