Cylindrical Roller Bearings SKF NU212 ECP/C3

The SKF NU212 ECP/C3 cylindrical roller bearing, measuring 60x110x22 mm, offers high radial load-carrying capacity as a non-locating bearing with increased clearance.

The NU212 ECP/C3 cylindrical roller bearing is a single-row rolling bearing designed for predominantly radial loads in mechanical and plant engineering. In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless and can be removed from both sides. This design allows axial length changes in the shaft to be compensated for freely within the bearing itself. An optimised internal design and the lightweight polyamide cage ensure quiet running.

In which applications does the NU212 ECP/C3 cylindrical roller bearing act as a non-locating bearing?

Designs with rotating shafts primarily use this rolling bearing as a non-locating bearing when axial thermal expansion of the shaft needs to be accommodated. Thanks to the line contact of the cylindrical rollers, the design can withstand high radial loads. This design is suitable for bearing arrangements where axial guidance is provided separately by a second bearing. As the inner ring can be withdrawn from both ends, this greatly simplifies the separate installation of both rings into the housing and shaft.

What properties do the polyamide cage and C3 clearance offer?

The designations ECP and C3 describe functional characteristics for demanding operating conditions. The polyamide cage is characterised by its low weight and dampens vibrations during operation. The increased radial clearance (C3) compensates for thermal differences between the inner and outer rings, as well as the effects of tight fits. This prevents stress build-up in the rolling element set. The open bearing is designed for a temperature range of -30 to +120 degrees and requires an external housing seal.
