NA 4928 – Needle bearing for defined guidance with minimal installation height
Quality that safeguards processes
Needle roller bearings can withstand high radial loads despite their very small radial installation space. They also run with low friction and provide precise shaft guidance. This makes them an ideal space-saving solution for smooth operation and repeatable results. Axial loads can be handled by a separate element if required.
Design and manufacturing quality
The design utilizes the linear contact of slim rollers. Furthermore, optimized profiling relieves stress on the edges, ensuring the cage guides the rollers evenly. Depending on the series, machined rings with an inner ring provide a defined counter-running surface. Full complement variants thus increase the load-bearing capacity. This design also incorporates an inner ring. In addition, the open sealing concept facilitates lubricant flow.
Convincing in everyday life
In practice, the compact design demonstrates high load-bearing capacity at stable temperatures and with low vibrations. Furthermore, easy-to-install versions reduce downtime and simplify maintenance. In addition, optimized lubrication, precise fits, and clean mating surfaces ensure consistently stable performance.
Summary
In short: slim, load-bearing and low-friction – for stable processes under radially dominant loads.
