Product Overview: The NN 3016 Double Row Cylindrical Roller Bearing
The NN 3016 is a high-precision, double-row cylindrical roller bearing, expertly engineered for applications demanding high rigidity and exceptional radial load capacity. With principal dimensions of 80x125x31mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NN 3000 Series line of Cylindrical Roller Bearings. Its design features two rows of cylindrical rollers, which provide excellent stiffness and support for heavy radial loads, making it ideal for high-speed, high-precision machinery. The NN design typically has three flanges on the inner ring and a flangeless outer ring, allowing for axial displacement of the shaft relative to the housing in both directions.
Key Features of the NN 3016 Bearing
- High Radial Load Capacity: The double-row roller design significantly increases the bearing's ability to handle heavy radial forces.
- Exceptional Rigidity: Provides a high degree of stiffness, which is crucial for maintaining rotational accuracy in precision applications.
- High-Speed Performance: Engineered for minimal friction and heat generation, enabling reliable operation at high rotational speeds.
- Axial Displacement Accommodation: The design allows the shaft to move axially relative to the housing, compensating for thermal expansion.
- Separable Design: The inner ring with the roller and cage assembly can be mounted separately from the outer ring, simplifying installation and maintenance.
- Precision Manufacturing: Produced to tight tolerances to ensure optimal performance, reliability, and extended service life.
Common Applications
- Machine Tool Spindles: Extensively used in the main spindles of lathes, milling machines, and grinding machines where high precision is paramount.
- Industrial Gearboxes: Provides robust support for gears and shafts in heavy-duty gear systems.
- Rolling Mills: Suitable for the demanding environment of steel and metal rolling mills.
- Printing Presses: Ensures the precise and stable rotation of cylinders in large-scale printing machinery.
- Vibrating Screens and Shakers: Capable of withstanding the heavy loads and vibrations common in quarrying and mining equipment.
- Large Electric Motors: Supports motor shafts under significant radial loads, ensuring smooth and efficient operation.
Benefits of Using the NN 3016 Bearing
- Enhanced Machine Accuracy: The high rigidity minimizes shaft deflection, leading to greater machining precision and product quality.
- Increased Reliability: Its robust construction and high load capacity reduce the risk of premature failure in demanding environments.
- Extended Service Life: Made from high-quality bearing steel, it offers excellent durability and wear resistance, prolonging the operational life of the machinery.
- Improved Operational Efficiency: Low friction characteristics contribute to reduced energy consumption and cooler running temperatures.
- Simplified Assembly: The separable nature of the bearing makes both mounting and dismounting processes more straightforward and efficient.
