Cylindrical Roller Bearings SKF NUP2209 ECP

The SKF NUP2209 ECP cylindrical roller bearing is a single-row fixed bearing measuring 45 × 85 × 23 mm, designed for high radial loads and axial guidance on both sides.

The NUP2209 ECP cylindrical roller bearing is an open, single-row rolling bearing with a bore of 45 mm, an outer diameter of 85 mm and a width of 23 mm. As a fixed bearing, this SKF design withstands high radial loads and also guides the shaft in both axial directions. The Explorer design features an optimised internal construction. The bearing operates with standard radial clearance within a temperature range of -30 to +120 °C.

For which loads is the NUP2209 ECP cylindrical roller bearing suitable as a fixed bearing?

This rolling bearing is suitable for bearing arrangements in which high transverse forces are accompanied by axial forces acting in both directions. Thanks to the line contact of the cylindrical rollers, the bearing absorbs high radial loads with high rigidity. The NUP geometry ensures precise guidance of the shaft in both axial directions relative to the housing. As there are no integrated seals, protection against contamination is provided by the surrounding housing.

What are the advantages of the NUP design with a polyamide cage?

Two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring, provide positive support for axial forces in both directions. The polyamide cage ensures low-friction guidance of the rolling elements and reduces the component weight. Dimensional accuracy to tolerance class P0 (ABEC 1) and running accuracy to P6 (ABEC 3) define the manufacturing tolerances for the operating temperature range of –30 to +120 °C.
