Cylindrical Roller Bearings SKF NU2307 ECP

The SKF NU2307 ECP cylindrical roller bearing is a single-row non-locating bearing with a 35 mm bore, a polyamide cage and an inner ring that can be removed from either side.

As a single-row roller bearing, the SKF NU2307 ECP cylindrical roller bearing can accommodate high radial loads. Thanks to the NU design, which features two fixed flanges on the outer ring and a flangeless inner ring, this version functions purely as a non-locating bearing. The bearing compensates for axial shaft movement directly inside the bearing. With key dimensions of a 35 mm bore, 80 mm outer diameter and 31 mm width, the SKF Explorer design is suitable for demanding industrial applications in mechanical engineering.

What is the NU2307 ECP cylindrical roller bearing suitable for in practice?

Design engineers primarily use the NU2307 ECP cylindrical roller bearing where high radial loads are present and axial thermal expansion of the shaft needs to be compensated for. As the inner ring can be removed from both sides, the rolling bearing can be fitted separately. Typical applications include bearing arrangements subject to high radial loads, as well as general mechanical engineering. The optimised internal design of the Explorer series ensures even load distribution across the raceways and reduces heat build-up during operation.

What are the characteristics of the polyamide cage in the ECP design?

The letter P in the ECP suffix stands for a polyamide cage that guides the cylindrical rollers. This material reduces the weight of the roller guide and ensures smooth running with low friction. The open bearing is designed for a temperature range of -30 to +120 degrees. As there are no integrated seals, you should incorporate the lubrication supply via the housing system and adapt the sealing to the specific operating environment.
