Product Overview: The NJ 244 Cylindrical Roller Bearing
The NJ 244 is a high-capacity single-row cylindrical roller bearing, featuring the standard dimensions of 220x400x65mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is part of the versatile NJ Series. Its design, which includes two integral flanges on the outer ring and one on the inner ring, allows it to accommodate high radial loads while also providing axial location for a shaft in one direction. The separable nature of the bearing, where the inner ring can be mounted independently of the outer ring, simplifies both installation and maintenance procedures, making it a practical choice for demanding industrial applications.
Key Features of the NJ 244 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways enables the bearing to support heavy radial loads.
- Single-Direction Axial Location: The flange configuration allows the bearing to guide and locate a shaft axially in one direction.
- Separable Design: The inner and outer rings can be mounted separately, which greatly simplifies the assembly and dismounting process.
- Low Friction Operation: Engineered with an optimized internal geometry to minimize friction, reduce heat generation, and improve operational efficiency.
- High Rigidity: Provides excellent radial stiffness, ensuring stability and precision in rotating machinery.
- Durable Construction: Manufactured from high-quality, clean bearing steel to ensure a long and reliable service life under tough conditions.
Common Applications
