SKF single-row cylindrical roller bearings, open design, NU 2307 ECP 35 x 80 x 31

Type NU, NJ, and NUP

Single-row SKF cylindrical roller bearings of the basic design are manufactured in many different versions, distinguished by the arrangement of the flanges on the inner and outer rings. The most common designs are:

Design NU
The bearings of design NU have two fixed flanges on the outer ring and a flange-less inner ring. The bearings allow axial displacement between the shaft and housing in both directions within the bearing.

Design NJ
Bearings of design NJ have two fixed flanges on the outer ring and a fixed flange on the inner ring. They can guide the shaft axially in one direction. Axial displacement of the shaft is only possible in one direction.

Design NUP
The bearings of design NUP have two fixed flanges on the outer ring as well as a fixed flange and a loose flange disc on the inner ring. The bearing secures the shaft axially in both directions and is therefore suitable for fixed bearing arrangements.
