Product Overview: The NJ 322 Cylindrical Roller Bearing
The NJ 322 is a high-capacity single-row cylindrical roller bearing, engineered to handle heavy radial loads and provide axial shaft location in one direction. With key dimensions of 110x240x50mm, this bearing is a vital component in our NJ Series of Cylindrical Roller Bearings. Its specific design features two integral flanges on the inner ring and a single flange on the outer ring, which allows it to accommodate axial displacement of the shaft relative to the housing in one direction while providing precise axial guidance in the other.
The separable design of the NJ 322 simplifies the mounting and dismounting process, as the inner ring with its roller and cage assembly can be installed independently of the outer ring. This feature is particularly advantageous in applications requiring frequent maintenance or tight-fit installations. Manufactured from high-quality bearing steel, this component ensures durability, low friction, and reliable performance in demanding industrial environments.
Features of the NJ 322 Bearing
- High Radial Load Capacity: Designed with a line contact between rollers and raceways to support substantial radial forces.
- Axial Location in One Direction: The flange configuration allows the bearing to locate the shaft axially in a single direction.
- Separable Design: The inner ring, rollers, and cage can be separated from the outer ring, facilitating easier installation and maintenance.
- Low Friction Operation: Precision engineering minimizes friction between the rollers and raceway flanges, allowing for high-speed operation.
- Durable Construction: Made from premium-grade bearing steel for enhanced strength, wear resistance, and a long operational lifespan.
- Accommodates Axial Displacement: Allows for axial displacement (e.g., from thermal expansion) in one direction between the shaft and housing.
Common Applications of NJ 322 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy radial loads common in gear systems.
- Pumps and Compressors: Ensures reliable rotation and support for shafts in high-pressure industrial pumps and compressors.
- Electric Motors: Used in large electric motors to support the rotor shaft and manage significant radial forces.
- Construction and Mining Equipment: Ideal for heavy machinery like excavators, loaders, and crushers where durability is critical.
- Rolling Mills: Withstands the extreme loads and high speeds found in steel and metal rolling applications.
- Wind Turbines: Supports the main shaft and gearbox components in wind energy generation systems.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed machine tool applications.
