Product Overview: The N 313 Cylindrical Roller Bearing
The N 313 Cylindrical Roller Bearing is a high-performance component designed for applications requiring high radial load capacity and accommodation for axial displacement. With dimensions of 65x140x33mm, this bearing is part of our N 300 Series within the broader Cylindrical Roller Bearings category. The 'N' designation indicates a specific design where the inner ring has two integral ribs, and the outer ring is ribless. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice as a non-locating bearing.
Manufactured from high-quality bearing steel, the N 313 is engineered for durability and reliability in demanding industrial environments. Its separable design, where the inner ring and roller assembly can be mounted independently of the outer ring, simplifies both installation and maintenance procedures. This bearing is a fundamental part of machinery in various sectors, ensuring smooth operation under heavy radial stresses.
Key Features of the N 313 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement Capability: The N-type design allows for axial movement of the shaft in both directions, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner ring with the roller and cage assembly can be separated from the outer ring, facilitating easy mounting and dismounting.
- High Stiffness: Provides a high degree of radial stiffness, making it suitable for applications requiring rotational accuracy and stability.
- Low Friction Operation: Precision engineering and optimized internal geometry minimize friction, reducing operational heat and energy consumption.
- Durable Construction: Made from robust, high-purity bearing steel to ensure a long and reliable service life.
Common Applications of N 313 Bearings
- Industrial Gearboxes: Used as non-locating bearings on shafts to support heavy gear loads while allowing for thermal expansion.
- Electric Motors: Commonly found on the non-locating end of large electric motor shafts to handle radial forces.
- Pumps and Compressors: Provides reliable support for rotating shafts in various types of industrial pumps and compressors.
