RNU 220 ECJ

RNU 220 ECJ – Cylindrical roller bearings for consistent quality in series production and test benches

Quality that safeguards processes
This bearing can withstand very high radial loads with low friction and, depending on its design, can handle limited axial forces. This results in smooth running and reproducible results. By carefully selecting the bearing clearance or preload, concentricity remains stable and quality can be predicted.

Design and manufacturing quality
The rollers provide bearing via line contact; the profile and flange geometry are designed for low edge pressure. The separable design allows for easy assembly and maintenance of the components. Depending on the design (NU, N, NJ, NUP), axial guidance is achieved via the flange design. A steel sheet cage is included in some versions (J).

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. Careful alignment is essential, as the angular adjustability is limited by the design.

Summary
Conclusion: high load-bearing capacity, low friction and easy assembly for stable, predictable processes in continuous use.
