Cylindrical Roller Bearings SKF NU212 ECP

The SKF NU212 ECP cylindrical roller bearing, measuring 60x110x22 mm, provides a robust support arrangement for accommodating purely radial forces.

This single-row NU212 ECP cylindrical roller bearing, part of the SKF Explorer performance class, accommodates radial forces in demanding industrial drives. Thanks to the line contact between the cylindrical rollers and the raceways, the design can handle high radial loads in continuous operation. As an open component without integrated seals, the bearing is designed for direct use in lubricated machine housings where lubricating oil or grease can circulate freely around the rolling elements.

What is the NU212 ECP cylindrical roller bearing suitable for in operation?

The bearing is designed for shaft positions where only radial loads occur and axial length compensation is required. Typical applications include industrial shaft mountings with a purely radial force flow, where thermal expansion must be accommodated without inducing stress. Thanks to its design as a non-locating bearing, the inner ring moves axially relative to the roller set, meaning that no axial forces act on the bearing assembly. The optimised internal design supports smooth rolling behaviour under operating conditions.

What are the advantages of the NU design and the polyamide cage?

The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed completely from both sides, which significantly facilitates separate installation onto the shaft and housing. The integrated polyamide cage is characterised by low moving masses, dampens operating noise and keeps friction levels low. During operation, the permissible temperature range of –30 to +120 degrees and the standard radial bearing clearance must be taken into account when selecting the fit.
