NA4904-2RSR-XL – Needle roller bearings for easy-to-assemble standard solutions
Quality that safeguards processes
Thanks to numerous slim rollers, needle bearings distribute the load over a large area, ensuring high radial load ratings with a low profile. Friction remains low, reducing operating temperature and energy consumption. The precise roller guidance ensures smooth running and reproducible results.
Design and manufacturing quality
The design relies on the linear contact of slim rollers, optimized profiling for edge relief, and precise cage guidance. Variants in the NA/NKI series integrate an inner ring, simplifying assembly and clearly defining the fit concept. Alternatively, versions without an inner ring are available; in this case, hardened and precision-machined shafts serve as the raceway. Depending on the design, sealed versions are available to retain lubricant within the bearing and reduce particle ingress. The cage is made of sheet steel, stabilizing the roller guidance and limiting friction peaks.
Convincing in everyday life
In operation, this results in high load-bearing capacity with a compact design and consistent vibration and temperature levels. Easy-to-assemble designs and suitable lubrication concepts help reduce downtime. Precise fits and carefully machined seating surfaces are essential for consistently stable performance.
Summary
Slim, load-bearing and low-friction – for stable processes under radially dominant loads.
