Cylindrical Roller Bearings SKF NU2315 ECP

The SKF NU2315 ECP cylindrical roller bearing is a single-row non-locating bearing with a 75 mm bore, a polyamide cage and a separable inner ring, designed for high radial loads.

As a single-row roller bearing, the NU2315 ECP withstands high radial loads and compensates for axial length changes in the shaft. In this Explorer version from SKF, the bearing features an optimised internal design. With key dimensions of a 75 mm bore, 160 mm outer diameter and 55 mm width, the design is engineered to handle demanding radial loads. The inner ring, which can be removed from both sides, facilitates installation and allows for separate fit selection for the shaft and housing.

In which applications does the NU2315 ECP cylindrical roller bearing act as a floating bearing?

This bearing is primarily used as a non-locating bearing when thermal length changes in the shaft need to be accommodated without constraint within the bearing housing. Typical applications include industrial bearing arrangements subject to high radial forces. As the outer ring has solid flanges and the inner ring is flangeless, the shaft moves axially relative to the housing without axial constraint.

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

The bearing’s polyamide cage is characterised by its low weight and elastic properties. This ensures that the rolling elements run with low vibration and quietly. The permissible temperature range is from –30 to +120 degrees Celsius. As this is an open bearing without an integrated seal, you should select the appropriate lubricant and ensure the housing is properly sealed to suit the specific operating environment.
