Product Overview: The NN 3013 Double Row Cylindrical Roller Bearing
The NN 3013 is a high-precision, double row cylindrical roller bearing engineered for applications demanding high rigidity and exceptional radial load capacity. With dimensions of 65x100x25mm, this bearing is a key component in our NN 3000 Series, part of the broader Cylindrical Roller Bearings category. The NN design features three integral flanges on the inner ring and a flangeless outer ring, which allows for axial displacement of the shaft relative to the housing in both directions. This makes it ideal for use as a non-locating or floating bearing in high-speed, high-precision machinery.
As a specialist supplier of industrial mechanical parts, we ensure our NN 3013 bearings meet stringent quality standards. Their robust construction and optimized internal geometry provide superior performance, reduced friction, and an extended service life, making them a reliable choice for the most demanding industrial environments, particularly in machine tool spindles and heavy-duty gearboxes.
Features of the NN 3013 Bearing
- High Radial Load Capacity: The double row of cylindrical rollers provides a large contact area, enabling the bearing to support very heavy radial loads.
- Exceptional Rigidity: Its compact, double-row design offers high stiffness, which is critical for maintaining accuracy in precision applications like machine tools.
- Accommodates Axial Displacement: The flangeless outer ring allows the shaft to move axially relative to the housing, compensating for thermal expansion.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Separable Design: The inner ring with the roller and cage assembly can be mounted independently of the outer ring, simplifying installation and maintenance procedures.
- Precision Manufacturing: Produced to tight tolerances to ensure high running accuracy and consistent performance under demanding conditions.
Applications of NN 3013 Bearings
- Machine Tool Spindles: Widely used as the main spindle bearing in lathes, milling machines, and grinding machines where precision and rigidity are paramount.
- Industrial Gearboxes: Provides robust support for gears and shafts in heavy-duty transmissions, ensuring reliable power transfer.
