Cylindrical Roller Bearings SKF NU215 ECP

The SKF NU215 ECP cylindrical roller bearing, measuring 75x130x25 mm, serves as a separable support bearing designed to withstand high radial loads.

The NU215 ECP cylindrical roller bearing is a single-row radial roller bearing from the SKF Explorer range with an optimised internal design. Designed as an open bearing, it transmits high radial loads directly via the line contact of the cylindrical rollers. The NU design is characterised by two fixed flanges on the outer ring, whilst the inner ring has no flanges. This allows the bearing to move axially and compensates for thermally induced changes in the length of the shaft within the housing without any binding.

What is the NU215 ECP cylindrical roller bearing suitable for?

This design accommodates purely radial forces during continuous rotational movement and allows for axial shaft movement. Relevant applications include industrial shaft bearings subject to thermal linear expansion. As the inner ring can be removed from both sides, this design is suitable for applications where separate installation of the inner and outer rings is required. This simplifies installation and inspection procedures in compact spaces.

What are the advantages of the polyamide cage and the NU design?

The integrated polyamide cage guides the rolling elements with low vibration and keeps the weight of the rotating components to a minimum. It is designed for operating temperatures ranging from –30 to +120 degrees. This design features a standard radial bearing clearance and dimensional accuracy to Class P0/PN (ABEC 1), combined with increased running accuracy to Class P6 (ABEC 3). As the bearing is supplied without seals, and without a groove or lubrication bore in the outer ring, you can precisely tailor the lubrication and external housing sealing to the operating environment.
