Cylindrical Roller Bearings SKF NU1005

The SKF NU1005 cylindrical roller bearing is a compact, single-row non-locating bearing with dimensions of 25 × 47 × 12 mm, designed for purely radial loads.

The SKF NU1005 cylindrical roller bearing has standardised dimensions with a 25 mm bore, a 47 mm outer diameter and a 12 mm width. As a single-row roller bearing with line contact, it can accommodate high radial loads. In rotating shaft guides, it serves as a load-bearing support where designs are subjected to high radial forces and precise guidance is required.

What is the NU1005 cylindrical roller bearing suitable for in operation?

This bearing is suitable for industrial applications in which purely radial forces occur and axial thermal expansion of the shaft needs to be compensated for. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. As a result, the component acts as a floating bearing in mechanical engineering, for example in the case of thermally induced length changes in mounted shafts. The open bearing requires external sealing of the housing environment to protect against contamination and moisture.

What are the characteristics of the NU design and the sheet steel cage?

The separable design simplifies assembly procedures, as the inner and outer rings can be mounted independently of one another onto the shaft and housing. Axial displacement between the shaft and housing is compensated for directly within the component. A dimensionally stable sheet steel cage guides the cylindrical rollers evenly and allows use within a temperature range of -30 to +150 degrees. With normal radial clearance, the component is designed for standard fits.
