Reliable operation with Skf bearings

Practical benefits

High radial load capacity: You support heavy radial loads efficiently thanks to the optimized single-row cylindrical roller design.
Single direction axial location: The NJ design allows you to safely locate the shaft axially in one direction.
Quick and easy mounting: You install and maintain components effortlessly due to the convenient separable ring design.

In a nutshell

The right choise for

With the Skf nj 203 ecp single-row cylindrical roller bearing, you ensure reliable operation under heavy radial loads and high rotational speeds. Measuring 17 x 40 x 12 mm, this compact bearing features an nj design that safely accommodates axial displacement in one direction. The glass-fibre reinforced polyamide cage (ECP) significantly reduces friction and heat generation. Thanks to the separable ring design, mounting and maintenance in electric motors, gearboxes, and pumps are fast and straightforward.
