NUP 311 ECM

NUP 311 ECM – Cylindrical roller bearings for high load capacity in a compact design

Quality that safeguards processes
This bearing accommodates very high radial loads with low friction and, depending on its design, can withstand limited axial forces. This results in smooth running and reproducible results. With optimized bearing clearance or defined preload, a robust process with repeatable results is achieved.

Design and manufacturing quality
Through linear contact and an optimized, logarithmic profile, the rollers distribute the load evenly. The flange design promotes lubrication, and the separable rings simplify assembly. In the NUP design, two flanges on the outer ring and one flange plus a loose flange disc on the inner ring ensure axial guidance in both directions. Depending on the version, a solid brass cage (M) is included.

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.
