NU 313 ECJ/C3 – Cylindrical roller bearings for consistent quality in series production and test benches
Quality that safeguards processes
This bearing transmits extreme radial loads with low friction and, in suitable versions, can also provide axial limiting. The result is smooth operation and reliable process windows. 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 line 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 steel cage is included (J). The internal bearing clearance corresponds to C3.
Convincing in everyday life
The systems benefit from high radial load capacity, smooth operation, and consistent measured values throughout their service life, even with varying operating profiles. 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.
