NU 2222 ECJ

NU 2222 ECJ – 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 load 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 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 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
In short: durable, low-friction and easy to assemble – for stable processes and reliable results in continuous operation.
