NA 4901 | XIC | Machined Type With IR | NA Series

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.
