NU 309 ECM – Cylindrical roller bearings for consistent quality in series production and test benches
Quality that safeguards processes
This bearing accommodates very high radial loads with low friction and, depending on its design, can withstand limited axial forces. This results in smooth running and reproducible results. With optimized bearing clearance or defined preload, a robust process with repeatable results is achieved.
Design and manufacturing quality
The cylindrical rollers run with linear contact; a logarithmic roller profile relieves stress on the edges. Precise flange guides promote the lubricating film, and separable rings facilitate assembly and inspection. In the NU design, two flanges on the outer ring guide the rollers, while the inner ring is flangeless; axial displacement is possible in both directions. Depending on the version, a solid brass cage (M) is included.
Convincing in everyday life
In operation, this results in high load-bearing capacity despite a compact design, stable temperature and vibration levels, and predictable quality even under fluctuating loads and speeds. Precise alignment remains important because angular adjustability is limited.
Summary
Conclusion: high load-bearing capacity, low friction and easy assembly for stable, predictable processes in continuous use.
