Product Overview: The NJ 2218 Cylindrical Roller Bearing
The NJ 2218 is a high-performance cylindrical roller bearing, engineered to support substantial radial loads and locate the shaft axially in a single direction. With dimensions of 90x160x40mm, this bearing is a key component in our NJ Series and the broader Cylindrical Roller Bearings collection. Its design features two integral flanges on the outer ring and a single flange on the inner ring, making it ideal for applications requiring shaft guidance in one direction while accommodating thermal expansion. The separable nature of the bearing, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation and maintenance procedures.
Manufactured from premium-grade bearing steel, the NJ 2218 ensures durability and consistent performance in demanding industrial environments. Its line contact geometry between the rollers and raceways provides high stiffness and operational reliability. Trust our expertise as a leading supplier of industrial components to provide the right bearing solutions for your machinery.
Key Features of the NJ 2218 Bearing
- High Radial Load Capacity: Engineered with a line contact design to effectively manage heavy radial forces.
- Single-Direction Axial Location: The single flange on the inner ring allows the bearing to locate a shaft axially in one direction.
