Cylindrical Roller Bearings SKF NJ226 ECP

The NJ226 ECP cylindrical roller bearing from SKF Rolling Bearings, measuring 130x230x40 mm, offers high radial load capacity and single-sided axial guidance when used as a support bearing.

The NJ226 ECP cylindrical roller bearing functions as a single-row rolling bearing for heavy radial forces in industrial gearboxes and drive applications. Thanks to the optimised internal design of the Explorer series, the bearing assembly can accommodate high radial main loads. At the same time, the NJ design allows the shaft to be fixed in the axial direction. As an open bearing without sealing elements, the bearing unit can be integrated directly into the machine’s lubrication circuit and supplied with grease or lubricating oil, depending on requirements.

What loads and movements does the NJ226 ECP cylindrical roller bearing accommodate?

The NJ design functions as a support bearing in demanding mechanical drive trains and industrial gearboxes. This design combines a high radial load-carrying capacity with the targeted absorption of axial forces from a single direction. As the unit is designed with an inner ring that can be removed from one side, the bearing allows for a defined axial displacement in the opposite direction. This enables thermal-induced changes in shaft length to be effectively compensated for during operation.

What are the characteristics of the polyamide cage in the NJ226 ECP cylindrical roller bearing?

The integrated polyamide cage reduces the rotating masses in the roller ring due to its low weight and promotes smooth, low-friction running of the cylindrical rolling elements. The bearing is designed for a temperature range of -30 to +120 degrees. Thanks to the separable inner ring, both bearing rings can be fitted independently onto the shaft and housing. This design feature significantly facilitates precise assembly as well as any necessary inspection and maintenance work.
