Product Overview: The NJ 313 Cylindrical Roller Bearing
The NJ 313 is a single-row cylindrical roller bearing engineered for high-performance industrial applications. With principal dimensions of 65x140x33mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NJ 300 Series. Its design features two integral flanges on the outer ring and a single flange on the inner ring, allowing it to accommodate high radial loads and locate the shaft axially in one direction. This makes it ideal for machinery where thermal expansion or mounting inaccuracies require some axial movement.
As a specialist in industrial components, we ensure our NJ 313 bearings are manufactured to the highest industry standards for reliability and longevity. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation and maintenance procedures.

Features of the NJ 313 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very heavy radial loads.
- Single-Direction Axial Location: The flange arrangement enables the bearing to guide the shaft axially in one direction, acting as a locating bearing.
- Separable Design: The inner ring is separable, which simplifies the mounting and dismounting process, especially for interference fits.
- High Stiffness: Its robust construction provides excellent rigidity, which is crucial for applications requiring high rotational precision.
- Low Friction Operation: Engineered with an optimized internal geometry that reduces friction, minimizes heat generation, and extends service life.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and resistance to wear and fatigue.
Applications of NJ 313 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy loads and high speeds typical in transmission systems.
- Electric Motors: Used as locating bearings on motor shafts to control axial movement while supporting significant radial forces.
- Pumps and Compressors: Ensures reliable operation of rotating components in industrial fluid and gas handling equipment.
- Construction and Mining Equipment: Ideal for heavy machinery like excavators, loaders, and crushers that operate under extreme load conditions.
- Machine Tool Spindles: Offers the rigidity and precision required for main spindles in lathes, milling machines, and grinders.
- Vibrating Screens and Shakers: Withstands the heavy, shock-like loads common in material processing and sorting machinery.
- Rolling Mills: Used in steel and metal processing to support rollers under immense pressure.
Benefits of Using the NJ 313 Bearing
- Enhanced Machine Reliability: Its ability to handle high loads prevents premature failure, reducing downtime and increasing productivity.
- Simplified Installation and Maintenance: The separable nature of the bearing allows for easier handling and fitting, saving time and labor costs.
- Extended Service Life: High-quality materials and low-friction design contribute to a longer operational lifespan for both the bearing and the equipment.
- Improved Operational Efficiency: Minimizes energy loss through friction, contributing to more efficient machine performance.
- Versatile Application Range: Suitable for a wide variety of heavy-duty industrial applications requiring both radial support and axial location.
- Accommodates Axial Displacement: Allows for axial displacement of the shaft relative to the housing in one direction, compensating for thermal expansion.
