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

NA 4900 The NA 4900 is the smallest standard machined‑ring needle roller bearing with inner ring in the “NA 49..” series, designed for very compact, low‑cross‑section radial load applications. Its small dimensions make it suitable for precision assemblies, small motors or pumps, and wherever minimal space and light loads are involved. Despite its compact size, it retains the typical advantages of needle roller bearings: high radial load capability relative to its size, smooth rotation, and reliable performance with proper lubrication.
