Reliable load performance with Skf

Practical benefits

High radial capacity: The cylindrical roller design accommodates heavy radial forces efficiently at high operating speeds.
Single direction location: The NJ design guides your shaft axially in one direction to handle specific thrust movements.
Quick separable installation: You can easily mount inner and outer rings independently to streamline machine maintenance.

In a nutshell

The right choise for

With the Skf nj 204 ecp single row cylindrical roller bearing, you achieve dependable performance under heavy radial loads in electric motors, gearboxes, pumps, and compressors. The nj design features two integral flanges on the outer ring and one on the inner ring to locate the rotating shaft axially in one direction. Its glass fibre reinforced polyamide cage (ECP) ensures smooth operation and reduced friction. Thanks to the separable inner and outer rings, mounting, dismounting, and maintenance operations are straightforward. With dimensions of 20 x 47 x 14 mm and standard normal radial internal clearance (CN), this open bearing is an ideal choice for oil- or grease-lubricated enclosed housings.
