Cylindrical Roller Bearings SKF NUP2211 ECP

The SKF NUP2211 ECP cylindrical roller bearing, measuring 55x100x25 mm, can accommodate high radial loads and serves as a compact fixed bearing.

The NUP2211 ECP cylindrical roller bearing is a single-row radial roller bearing in the SKF Explorer performance class. Designed with an optimised internal geometry and a polyamide cage, this open bearing is suitable for applications involving high radial forces. The NUP design features two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring. As a result, the roller bearing guides the shaft in both axial directions within the housing.

In which installation situations does the NUP2211 ECP cylindrical roller bearing act as a fixed bearing?

This design is recommended when shaft assemblies must accommodate not only high radial forces but also axial guidance forces in both directions. The bearing acts as a fixed bearing, which often eliminates the need for separate axial bearings at the respective installation point. Thanks to its open design without a seal, the rolling bearing can be integrated directly into existing oil or grease lubrication circuits.

What are the key features of the polyamide cage and the NUP design?

The polyamide cage guides the cylindrical rollers with low friction and keeps the weight of the rotating components to a minimum. The NUP design also simplifies assembly: the inner and outer rings can be fitted separately onto the shaft and housing before the loose flange ring is inserted. With standard radial bearing clearance, dimensional accuracy to tolerance class P0 (ABEC 1) and running accuracy P6 (ABEC 3), the bearing fits into standardised fitting systems.
