Cylindrical Roller Bearings SKF NUP2213 ECP

The SKF NUP2213 ECP cylindrical roller bearing, with compact dimensions of 65 × 120 × 31 mm, accommodates high radial loads as well as axial guidance forces on both sides.

The NUP2213 ECP cylindrical roller bearing is a single-row rolling bearing with an optimised internal design for demanding mechanical bearing applications. In the Explorer version, this open bearing combines precise roller guidance with a flexible polyamide cage. Thanks to the NUP design, the bearing arrangement acts as a fixed bearing, axially securing shafts in both directions. It is installed in enclosed housing designs with existing oil or grease lubrication.

What loads can the NUP2213 ECP cylindrical roller bearing withstand?

This bearing is primarily used in bearing arrangements subject to high radial forces and axial guidance of the shaft. Thanks to the line contact between the cylindrical rollers and the raceways, the design can handle high radial loads without excessive edge pressure. At the same time, the flanges on the outer and inner rings absorb axial forces caused by alternating loads on the shaft. The permissible temperature range is from –30 to +120 degrees.

What is the function of the fixed bearing design and the polyamide cage?

The NUP design features two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring. As a result, the bearing fixes the shaft in its axial position on both sides, which often eliminates the need for separate axial bearing arrangements. The polyamide cage guides the rolling elements quietly and reduces the weight of the component. The combination of standard dimensional accuracy to P0/PN (ABEC 1) and running accuracy P6 (ABEC 3) ensures low-vibration operation with standard radial bearing clearance.
