Cylindrical Roller Bearings SKF NJ2216 ECP

The NJ2216 ECP cylindrical roller bearing from SKF Rolling Bearings, with an 80 mm bore and a polyamide cage, provides a robust bearing solution for high radial loads.

As a single-row cylindrical roller bearing, the NJ2216 ECP can accommodate very high radial loads. Thanks to its cylindrical rolling elements, the design is suitable for withstanding high forces. In the Explorer version, this roller bearing features an optimised internal design that reduces friction and improves running characteristics. As an open component without an integrated seal, it is designed for operation in oil- or grease-lubricated systems.

What is the NJ2216 ECP cylindrical roller bearing suitable for in operation?

This roller bearing is primarily used where heavy radial forces act on rotating shafts. The NJ design has two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the unit functions as a support bearing: it supports radial loads and guides the shaft in an axial direction. At the same time, the bearing compensates for axial length changes in the opposite direction without constraint, which helps to prevent stress build-up due to thermal expansion of the shaft.

What advantages do the polyamide cage and the NJ design offer during assembly?

The lightweight polyamide cage reduces the moving masses in the rolling element set. This promotes smooth running within the permissible temperature range of -30 to +120 degrees Celsius. As the inner ring can be removed from one side, the bearing rings can be fitted separately. This simplifies installation in cases of tight fits. With dimensional accuracy to P0/ABEC 1 and improved running accuracy to P6/ABEC 3, the bearing meets demanding requirements for concentricity.
