Product Overview: The NJ 205 Cylindrical Roller Bearing
The NJ 205 bearing is a high-capacity single-row cylindrical roller bearing, designed with principal dimensions of 25x52x15mm. As a key component in our Cylindrical Roller Bearings range, and specifically part of the NJ 200 Series, this bearing is engineered to accommodate heavy radial loads at high speeds. Its unique NJ design features two integral flanges on the outer ring and a single flange on the inner ring, enabling it to provide axial location for a shaft in one direction. This makes it an excellent choice for applications requiring both robust radial support and single-direction axial positioning.
Manufactured from high-quality bearing steel, the NJ 205 offers exceptional durability and reliability in demanding industrial environments. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies both installation and maintenance procedures. Trust our expertise as a leading supplier of industrial mechanical parts to provide high-performance bearings for your machinery.
Key Features of the NJ 205 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial forces.
- Single-Direction Axial Location: The flange arrangement on the inner and outer rings securely locates the shaft axially in one direction.
- Separable Design: Allows the inner ring to be mounted separately from the outer ring and cage assembly, facilitating easier installation and inspection.
- High-Speed Performance: Engineered with an optimized internal geometry that reduces friction, making it suitable for high-speed operation.
- Durable Construction: Made from premium-grade, through-hardened bearing steel for extended service life and resistance to wear.
- Dimensional Stability: Precision manufacturing ensures consistent dimensions for interchangeability and reliable performance.
Common Applications
- Industrial Gearboxes: Provides rigid support for gear shafts, handling the high radial loads common in gear systems.
- Pumps and Compressors: Used to support rotating shafts in industrial pumps and compressors, ensuring efficient operation.
- Electric Motors: Ideal for non-locating bearing positions in larger electric motors where thermal expansion of the shaft occurs.
- Machine Tool Spindles: Offers the rigidity and precision required for high-performance machine tools like lathes and milling machines.
- Automotive Transmissions: Employed in gear sets to manage radial loads and maintain shaft alignment.
- Vibrating Machinery: Suitable for use in vibratory rollers and screens due to its robust design and ability to handle heavy loads.
- Construction Equipment: Found in various heavy-duty machinery where reliable radial support is critical.
Benefits of Using the NJ 205 Bearing
