Cylindrical Roller Bearings SKF NU2210 ECP/C3

The SKF NU2210 ECP/C3 cylindrical roller bearing, designed as a free bearing with a 50 mm bore, withstands high radial loads whilst minimising friction.

The NU2210 ECP/C3 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. The combination of a 50 mm bore, 90 mm outer diameter and 23 mm width provides a compact design with a high load-carrying capacity. Thanks to its optimised internal design and lightweight polyamide cage, the bearing operates with low vibration. In this open design without seals, lubrication is provided by the surrounding machinery within a temperature range of -30 to +120 degrees Celsius.

What is the NU2210 ECP/C3 cylindrical roller bearing suitable for in operation?

Typical applications for this radial bearing include shaft mountings where significant radial loads occur. The NU design functions purely as a non-locating bearing. As the inner ring has no flanges and can be removed from either side, the bearing compensates for axial length changes in the shaft directly within the bearing itself. This feature helps to prevent stress build-up in the shaft assembly when components heat up during operation. Furthermore, the ability to dismantle the bearing simplifies the assembly of the shaft and housing.

What are the advantages of the ECP cage and the C3 clearance?

The suffixes denote material- and function-specific features for demanding operating conditions. The abbreviation ECP refers to an optimised internal geometry with a dimensionally stable polyamide cage, which dampens running noise and reduces friction. The increased radial clearance (C3) provides additional leeway for thermal expansion at high speeds or with tight fits. In combination with dimensional accuracy class P0 and increased running accuracy class P6, the bearing operates with dimensional stability and precise guidance.
