Product Overview: The NJ 240 Cylindrical Roller Bearing
The NJ 240 is a single-row cylindrical roller bearing engineered for high-performance industrial applications. With principal dimensions of 200mm Bore Diameter, 310mm Outer Diameter, and 70mm Thickness, this bearing is part of our comprehensive NJ Series of Cylindrical Roller Bearings. The NJ design features two integral flanges on the outer ring and a single flange on the inner ring, enabling it to accommodate heavy radial loads while providing axial location for a shaft in one direction. Its robust construction ensures reliability and longevity in the most demanding environments.
As a specialist supplier of industrial mechanical parts, we guarantee that our NJ 240 bearings meet stringent industry standards for precision and quality. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation and maintenance procedures. This feature is particularly advantageous in applications requiring frequent mounting and dismounting. Explore our full range of cylindrical roller bearings to find the ideal solution for your machinery.
Features of the NJ 240 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the accommodation of very high radial forces.
- Single-Direction Axial Location: Designed with an integral flange on the inner ring to guide the shaft axially in one direction.
- Separable Design: The inner ring is separable from the outer ring and roller assembly, facilitating easier mounting, dismounting, and inspection.
- Low Friction Operation: Optimized internal geometry minimizes friction and heat generation, leading to higher operational efficiency and speed capability.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and resistance to wear and fatigue.
- High Precision: Engineered to tight tolerances to ensure smooth, reliable performance and extended service life.
Applications of NJ 240 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial loads common in power transmission systems.
- Electric Motors and Generators: Used as locating bearings to support motor shafts and maintain precise rotor alignment.
- Pumps and Compressors: Ensures reliable rotation of impellers and crankshafts under heavy operational loads.
- Construction Machinery: Ideal for heavy equipment such as excavators, cranes, and bulldozers where durability is critical.
- Rolling Mills: Withstands the extreme forces and high temperatures found in steel and metal processing applications.
- Mining and Quarrying Equipment: Supports components in crushers, screens, and conveyor systems operating in harsh conditions.
- Pulp and Paper Machinery: Used in rollers and presses that require high load capacity and reliable performance.
- Wind Turbines: Supports the main shaft and gearbox components in wind energy generation systems.
Benefits of Using the NJ 240 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy loads and provide axial stability reduces the risk of component failure.
- Simplified Assembly and Maintenance: The separable nature of the bearing streamlines installation and inspection processes, reducing downtime.
- Improved Operational Efficiency: Low-friction characteristics contribute to reduced energy consumption and cooler running temperatures.
- Extended Service Life: High-quality materials and precision manufacturing result in a longer operational lifespan for the bearing and associated machinery.
- Versatile Shaft Guidance: Effectively locates the shaft in one direction, often paired with another bearing (like an NU 240) to manage axial movement in the other direction.
- Optimal Performance in Demanding Conditions: Built to withstand the rigors of heavy industry, ensuring consistent performance under stress.
