Cylindrical Roller Bearings SKF NU214 ECP/C3

The SKF NU214 ECP/C3 single-row cylindrical roller bearing, with a 70 mm bore and increased bearing clearance, is designed as a non-locating bearing for high radial loads.

This SKF NU214 ECP/C3 cylindrical roller bearing is designed as an open, single-row radial roller bearing for demanding mechanical loads. Thanks to the line contact between the rolling elements and raceways, the design can accommodate considerable radial forces. With an outer diameter of 125 mm and a width of 24 mm, the unit complies with standard industrial mounting dimensions. The outer ring has solid flanges, whilst the inner ring is flangeless, allowing for axial displacement during operation.

What are the industrial applications of the NU214 ECP/C3 cylindrical roller bearing?

As a classic floating bearing, the NU design compensates for heat-induced length changes in rotating shafts directly within the bearing housing. Typical applications can be found in general mechanical engineering as well as in drive systems subject to high radial loads. The integrated polyamide cage maintains the rollers at a defined distance, dampens running noise and contributes to smooth running. As the component is supplied in an open design, it requires lubrication via the surrounding housing structure, for example by means of an oil circulation system or targeted grease filling.

What are the key features of the version with C3 clearance and a polyamide cage?

The suffixes ECP and C3 describe key technical parameters. The abbreviation C3 denotes a slightly increased radial bearing clearance compared with the standard version. This increased clearance is intended to prevent the rolling elements from becoming stressed when tight shaft fits are installed or when operational temperature differences occur between the inner and outer rings. The polyamide cage (ECP), together with the optimised internal geometry, enables an permissible operating range of -30 to +120 degrees Celsius.
