Product Overview: The NJ 2224 Cylindrical Roller Bearing
The NJ 2224 is a high-capacity cylindrical roller bearing designed for demanding industrial applications. With principal dimensions of 120mm bore diameter, 215mm outer diameter, and 40mm thickness, this bearing is engineered to handle substantial radial loads and locate the shaft axially in one direction. As a key component in our NJ 2200 Series, the NJ 2224 is part of a versatile family of Cylindrical Roller Bearings. Its design, featuring two integral flanges on the outer ring and a single flange on the inner ring, makes it ideal for applications requiring both heavy radial support and single-direction axial positioning. The separable nature of the inner ring simplifies mounting and maintenance procedures, a crucial advantage in complex machinery.
Key Features of the NJ 2224 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very high radial forces.
- Single-Direction Axial Location: Designed to guide and support a shaft axially in one direction, preventing unwanted movement.
- Separable Design: The inner ring can be mounted independently of the outer ring and roller assembly, facilitating easier installation, inspection, and maintenance.
- High Stiffness: Provides excellent rigidity, making it suitable for applications where minimal deflection is critical under heavy loads.
- Low Friction Operation: Engineered for efficient performance, minimizing rotational friction and heat generation for enhanced service life.
- Robust Construction: Manufactured from high-quality bearing steel to ensure durability and reliability in harsh industrial environments.
