Cylindrical Roller Bearings SKF NUP306 ECP

The SKF NUP306 ECP cylindrical roller bearing is an open, fixed bearing with dimensions of 30x72x19 mm, designed for high radial loads.

This single-row NUP306 ECP cylindrical roller bearing combines a high radial load capacity with precise shaft guidance. The bearing has a cylindrical bore of 30 mm, an outer diameter of 72 mm and a width of 19 mm. Thanks to the Explorer design with an optimised internal structure, the bearing can cope with demanding operating conditions. As this is an open design without an integrated seal, the component can be flexibly integrated into lubricated housing designs.

How does the NUP306 ECP cylindrical roller bearing absorb radial and axial forces?

Design engineers primarily use this bearing where strong radial forces are present and axial fixation of the shaft is required at the same time. The NUP design features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. As a result, the bearing arrangement absorbs axial forces from both directions and functions as a true fixed bearing. The design is suitable for industrial bearing arrangements subject to high radial loads with axial fixation on both sides.

What are the key features of the NUP design with a polyamide cage?

The integrated polyamide cage guides the cylindrical rollers with low friction and ensures quiet operation. The permissible temperature range is from –30 to +120 degrees. The bearings are manufactured with standard radial clearance, dimensional accuracy class P0/PN (ABEC 1) and enhanced running accuracy to tolerance class P6 (ABEC 3). For installation, this means high concentricity with standardised mounting dimensions. For open bearings, always ensure clean assembly and external sealing of the assembly.
