Cylindrical Roller Bearings SKF NU2312 ECP

The SKF NU2312 ECP cylindrical roller bearing, measuring 60x130x46 mm, offers a radial load-capable floating bearing arrangement with a removable inner ring.

The SKF NU2312 ECP cylindrical roller bearing is a single-row rolling bearing in the Explorer design with an optimised internal construction. Thanks to the line contact of the cylindrical rollers, this design can accommodate very high radial forces. The open bearing has a bore of 60 mm, an outer diameter of 130 mm and a width of 46 mm, and operates within a temperature range of -30 to +120 degrees.

When is the NU2312 ECP cylindrical roller bearing suitable as a floating bearing?

This bearing is primarily used in bearing arrangements where temperature-induced changes in shaft length must be compensated for without constraint. The outer ring has two fixed guide flanges, whilst the inner ring is flangeless and removable from both sides. This allows the axial displacement of the shaft to be accommodated directly within the bearing. Typical applications are found in bearing arrangements subject to purely radial loads.

What are the advantages of a polyamide cage and a removable inner ring?

The combination of separately mountable rings and an elastic polyamide cage simplifies maintenance and assembly. You can mount the inner and outer rings separately onto the shaft and housing, which reduces the risk of assembly errors. The lightweight cage guides the rollers quietly and is suitable for standard radial bearing clearance. In terms of dimensional accuracy, the component complies with tolerance class P0/PN (ABEC 1), whilst the running accuracy of P6 (ABEC 3) ensures smooth running. Please note that this open bearing must be externally lubricated and sealed via the housing design.
