NJ 2215 ECJ/C3 – Cylindrical roller bearings for reliable results under varying operating conditions

Quality that safeguards processes
This bearing is designed for high radial loads and low friction; depending on the flange design, it also allows for axial guidance. This ensures consistent running accuracy and results. The bearing clearance or a defined preload can be selected according to the application and supports process reliability.

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 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 cage is included (J). The internal bearing clearance corresponds to C3.

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.
