Cylindrical Roller Bearings SKF NUP2311 ECP

The SKF NUP2311 ECP cylindrical roller bearing, with a 55 mm bore and an outer diameter of 120 mm, offers high radial load-carrying capacity and axial guidance on both sides.

The NUP2311 ECP cylindrical roller bearing is a single-row rolling bearing in the Explorer design with an optimised internal construction. The NUP design features two fixed flanges on the outer ring and a fixed flange with a loose flange disc on the inner ring. As a result, the open bearing can accommodate not only high radial forces but also axial loads from both directions, and serves as a compact fixed bearing for guiding shafts in mechanical assemblies.

What is the NUP2311 ECP cylindrical roller bearing suitable for?

This bearing design is primarily used in bearing arrangements where rotating shafts must be precisely fixed axially whilst simultaneously withstanding very high radial loads. Due to the line contact between the rollers and raceways, the roller bearing absorbs considerable radial forces. The integrated polyamide cage dampens vibrations in the system and promotes smooth running even under varying load conditions.

What are the distinctive features of the version with a polyamide cage?

The suffix ECP stands for an optimised internal design in combination with a polyamide cage. This cage design ensures low-friction roller movement and has a low weight. To ensure safe operation, the thermal operating range of -30 to +120 degrees Celsius must be observed. As the roller bearing is of an open design and the outer ring is supplied without a groove or lubrication bore, the housing seal and lubricant supply in the surrounding environment must be suitably designed.
