Product Overview: The NJ 203 Cylindrical Roller Bearing
The NJ 203 is a high-performance single-row cylindrical roller bearing, a key component in our NJ 200 Series lineup. With dimensions of 17x40x12mm, this bearing is engineered to handle high radial loads and accommodate axial displacement in one direction. Its distinctive design features two integral flanges on the outer ring and a single flange on the inner ring, which allows it to locate the shaft axially. The separable nature of the bearing—where the inner ring can be mounted independently of the outer ring and roller assembly—greatly simplifies both installation and maintenance procedures. This makes the NJ 203 a preferred choice for applications demanding robust performance and easy handling.
As a specialist supplier of industrial mechanical parts, we ensure our NJ 203 bearings are manufactured to the highest industry standards, providing reliability and longevity. Explore our comprehensive collection of Cylindrical Roller Bearings to find the ideal solution for your machinery.
Key Features of the NJ 203 Bearing
