NA 6906

The NA 6906 is a high-performance needle roller bearing designed to handle heavy radial loads while operating in compact spaces. Its full-complement needle roller arrangement provides excellent rigidity and load distribution, making it suitable for high-demand applications such as industrial machinery, gearboxes, pumps, and automotive components. Built from premium bearing steel, the NA 6906 offers reliability, low friction, and long service life even under continuous or high-speed operation.

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.
