Product Overview: The NJ 324 Cylindrical Roller Bearing
The NJ 324 Cylindrical Roller Bearing is a high-performance component engineered to manage substantial radial loads and provide axial location for a shaft in one direction. With its principal dimensions of 120x260x55mm, this bearing is part of our comprehensive NJ 300 Series within the broader Cylindrical Roller Bearings category. The NJ design features two integral flanges on the inner ring and one on the outer ring, making it ideal for applications requiring shaft guidance. Its separable design simplifies both mounting and dismounting, allowing the inner ring to be fitted independently of the outer ring and roller assembly.
Manufactured to exacting industry standards, the NJ 324 bearing ensures reliability and a long service life in demanding industrial environments. It is a critical component in machinery where both high radial forces and single-direction axial positioning are essential for operational integrity.
Key Features of the NJ 324 Bearing
- Single-Direction Axial Location: The flange arrangement allows the bearing to locate the shaft axially in one direction.
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Separable Design: Inner and outer rings can be mounted separately, simplifying installation, inspection, and maintenance procedures.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, making it suitable for high-speed applications.
- Axial Displacement Accommodation: Can accommodate axial displacement of the shaft relative to the housing in the non-locating direction.
- Durable Construction: Made from high-purity, hardened bearing steel for exceptional durability and resistance to wear.
Common Applications of NJ 324 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, ensuring precise alignment and power transmission.
- Pumps and Compressors: Used in heavy-duty pumps where radial loads and shaft location are critical.
- Electric Motors and Generators: Supports motor shafts, handling the high radial forces generated during operation.
- Construction Machinery: Essential in equipment like excavators, cranes, and loaders for reliable performance.
- Machine Tool Spindles: Ensures the rigidity and rotational accuracy required in lathes, mills, and grinding machines.
- Vibrating Screens and Crushers: Withstands the heavy shock loads and vibrations common in mining and aggregate processing.
- Rolling Mills: Used to support the work rolls and back-up rolls in steel and metal processing plants.
