NJ 220 ECJ/C4P – Cylindrical roller bearings for stable concentricity in high-load applications

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 rollers bear weight 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. In the NJ design, two flanges on the outer ring and one flange on the inner ring guide the rollers; axial guidance is provided in one direction. Depending on the version, a steel sheet cage is included (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. 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.
