NU 421 M – Cylindrical roller bearings for consistent quality in series production and test benches
Quality that safeguards processes
This bearing combines high radial load capacity with efficient friction characteristics; variants with a suitable flange design provide limited axial guidance and ensure smooth running. By carefully selecting the bearing clearance or preload, concentricity remains stable and quality can be predicted.
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 practice, the bearings impress with their high load-bearing capacity despite their low profile, consistent temperatures, and reproducible values – even under changing conditions. Careful alignment is essential, however, as the angular adjustability is limited by design.
Summary
Conclusion: high load-bearing capacity, low friction and easy assembly for stable, predictable processes in continuous use.
