Product Overview: The NN 3036 Double Row Cylindrical Roller Bearing
The NN 3036 is a high-precision, double row cylindrical roller bearing, part of the acclaimed NN 3000 Series. With dimensions of 180x280x74mm, this bearing is engineered to handle extremely high radial loads and operate at high speeds, making it a critical component in demanding industrial machinery. Its design features two rows of rollers, providing exceptional rigidity and stability. The NN 3036 is a non-locating bearing, meaning it accommodates axial displacement of the shaft relative to the housing, which is essential for managing thermal expansion. As a leading supplier of industrial components, we provide top-quality Cylindrical Roller Bearings manufactured to precise industry standards for optimal performance and reliability.
Key Features of the NN 3036 Bearing
- Exceptional Radial Load Capacity: The double row design allows it to support very heavy radial loads, far exceeding that of single row bearings.
- High Rigidity: Two rows of rollers provide a stiff bearing arrangement, crucial for applications requiring high rotational accuracy, such as machine tool spindles.
- High-Speed Performance: Engineered for minimal friction and heat generation, enabling reliable operation at high rotational speeds.
- Accommodates Axial Displacement: The inner and outer rings can move axially relative to each other, compensating for shaft expansion or contraction.
- Separable Design: The outer ring is separable from the inner ring and roller assembly, simplifying the mounting and dismounting process.
- Precision Manufacturing: Built to tight tolerances to ensure high running accuracy and consistent performance in precision equipment.
Common Applications
- Machine Tool Main Spindles: Widely used in lathes, milling machines, and grinding machines where high precision and stiffness are paramount.
- Rolling Mills: Ideal for support rolls and work rolls in steel and metal processing plants due to its high load capacity.
- Heavy-Duty Gearboxes: Provides robust support for shafts in large industrial transmission systems.
- Printing Machinery: Ensures smooth and accurate rotation of printing cylinders and rollers under heavy loads.
- Large Electric Motors and Generators: Supports rotor shafts in high-power electrical machinery.
- Pumps and Compressors: Used in heavy industrial pumps that operate under severe conditions.
- Marine Propulsion Systems: Provides reliable support in marine gearbox and shaft applications.
Benefits of Using the NN 3036 Bearing
