The NJ 304 is a high-performance single-row cylindrical roller bearing, engineered to support heavy radial loads and high-speed operation. With principal dimensions of 20x52x15mm, this bearing is a key component in our NJ 300 Series. Its design is part of the broader Cylindrical Roller Bearings category, known for their exceptional load-carrying capacity and rigidity.
1. Exceptional Radial Load Capacity: The cylindrical roller design maximizes contact area with raceways, enabling the bearing to withstand extremely high radial loads—far exceeding deep groove ball bearings of the same size—suitable for heavy-duty mechanical operations.
2. Separable Structure for Easy Maintenance: Inner and outer rings can be disassembled separately, allowing quick mounting/dismounting without removing adjacent components, simplifying inspection, lubrication, and replacement.
3. High-Speed Adaptability: Precision-machined rollers and optimized cage design minimize friction and centrifugal force at high speeds, ensuring stable operation even under rapid rotation, with low heat generation.
4. Stable & Durable Performance: Made of high-strength bearing steel with heat treatment, it boasts excellent wear resistance and rigidity. The flange structure on the outer ring prevents axial displacement, enhancing operational stability.
1. Industrial Gearboxes & Transmissions: Essential for heavy-duty gearboxes in mining machinery, construction equipment, and industrial reducers, bearing radial loads from gear meshing and ensuring smooth power transmission.
2. Automotive Components: Used in automotive gearboxes, drive shafts, and differential systems, adapting to high-speed rotation and frequent load changes during vehicle operation.
3. Machine Tools & Processing Equipment: Applied in spindle components of lathes, milling machines, and drilling machines, supporting radial loads while maintaining high rotational accuracy for precise machining.
4. Heavy-Duty Pumps & Compressors: Suitable for rotating shafts of industrial pumps, air compressors, and fans, withstanding continuous radial loads and harsh working conditions to ensure long-term reliable operation.
Our robust production capability allows us to provide a wide array of solutions, helping you reduce downtime and enhance operational reliability.
