RNA6909-ZW-XL – Needle roller bearing for tight installation space with high radial load
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. The contact geometry is designed for low friction and stabilizes temperature behavior. At the same time, the defined roller guidance ensures smooth running and repeatable results.
Design and manufacturing quality
The design relies on the linear contact of slim rollers, optimized profiling for edge relief, and precise cage guidance. Versions in the NK/RNA series utilize the hardened and precision-machined shaft as the inner raceway, eliminating the need for an inner ring and further reducing the overall height. Alternatively, versions with an inner ring are available for applications requiring specific fit ratios. The cage is made of sheet steel, which stabilizes the roller guidance and limits friction peaks.
Convincing in everyday life
This results in high load reserves in a small installation space and smooth, temperature-stable operation. Easy-to-install versions and readily accessible lubrication points reduce downtime. Precise fits and carefully machined mating surfaces are essential for consistently stable performance.
Summary
Space-saving, load-bearing and smooth-running – for reproducible results under radial main load.
