Product Overview: The N 307 Cylindrical Roller Bearing
The N 307 is a single-row cylindrical roller bearing engineered for high performance in demanding industrial applications. With key dimensions of 35x80x21mm, this bearing is a crucial component in our N 300 Series, part of the broader Cylindrical Roller Bearings category. The N-type design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion or potential mounting inaccuracies.
As a specialist supplier of industrial components, we ensure our N 307 bearings meet stringent quality standards. Their design is optimized to handle high radial loads and operate at high speeds, providing exceptional reliability and a long service life. The separable nature of the bearing, where the outer ring can be mounted independently from the inner ring and roller assembly, significantly simplifies installation and maintenance procedures.
Key Features of the N 307 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement: The N-type design accommodates axial movement in both directions, compensating for shaft expansion or contraction.
- Separable Design: The inner and outer rings can be mounted separately, simplifying installation, inspection, and maintenance routines.
- High Stiffness: Provides a high degree of rigidity, making it suitable for precision applications like machine tool spindles.
- Low Friction Operation: Advanced roller and raceway profiling reduces friction and heat generation, enabling higher operational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for excellent fatigue resistance and longevity.
Common Applications of N 307 Bearings
- Industrial Gearboxes: Used on non-locating shafts to support heavy radial loads while allowing for thermal expansion.
- Electric Motors: Ideal for larger electric motors where shaft elongation can occur during operation.
- Pumps and Compressors: Provides robust support for rotating shafts in various industrial pump and compressor designs.
- Construction and Mining Equipment: Employed in heavy machinery where durability and high load capacity are critical.
- Vibrating Screens and Shakers: Withstands the heavy radial forces and high-speed rotations typical in vibratory machinery.
- Machine Tool Spindles: Offers the necessary rigidity and precision for high-accuracy machining operations.
- Rolling Mills: Used in steel and other material processing mills to handle extreme radial loads.
Benefits of Using the N 307 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy loads and accommodate axial shifts reduces stress on the entire assembly, minimizing downtime.
- Simplified Installation and Maintenance: The separable components make mounting and dismounting straightforward, saving time and labor costs.
- Extended Service Life: The robust design and low-friction characteristics lead to less wear and a longer operational lifespan.
- Improved Performance at High Speeds: Engineered for minimal heat generation, allowing for efficient and reliable high-speed operation.
- Versatility in Design: Suitable as a non-locating bearing, providing engineers with flexibility in machine design and assembly.
- Prevents Thermal Stress: By allowing the shaft to move axially, it prevents the buildup of internal stresses caused by temperature variations.
