Product Overview: The NU 2213 Cylindrical Roller Bearing
The NU 2213 is a high-capacity single-row cylindrical roller bearing, engineered to handle heavy radial loads and high-speed operation. With dimensions of 65x120x31mm, this bearing is a key component in our NU 2200 Series collection. A defining feature of the NU design is its ability to accommodate axial displacement of the shaft relative to the housing in both directions. This is achieved because the inner ring has no flanges, allowing for free axial movement, which is essential for applications with thermal expansion or potential mounting inaccuracies. As a premier supplier of industrial components, we provide top-quality Cylindrical Roller Bearings that ensure reliability and performance in the most demanding industrial environments.
Key Features of the NU 2213 Bearing
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance procedures.
- High Radial Load Capacity: The line contact between the rollers and raceways allows this bearing to support heavy radial loads.
- Axial Displacement Accommodation: The flangeless inner ring design permits axial movement, effectively compensating for shaft expansion or contraction due to temperature changes.
- High-Speed Capability: Engineered with low-friction characteristics, the NU 2213 is suitable for applications requiring high rotational speeds.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and a long service life.
- Dimensional Stability: Precision manufacturing ensures tight tolerances and consistent performance, contributing to overall machine reliability.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors and Generators: Used as non-locating bearings on motor shafts to allow for thermal expansion.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps and compressors operating under heavy loads.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed machine tool applications.
- Construction and Mining Equipment: Withstands the harsh conditions and heavy loads found in machinery like excavators, conveyors, and crushers.
- Rolling Mills: Capable of managing the extreme radial forces present in steel and metal processing machinery.
- Vibrating Screens and Shakers: The bearing's durability makes it ideal for the high-vibration environment of screening equipment.
Benefits of Using the NU 2213 Bearing
- Enhanced Machine Uptime: The ability to handle heavy loads and accommodate axial displacement reduces the risk of premature failure, leading to less downtime.
- Simplified Assembly: The separable nature of the bearing makes both mounting and dismounting straightforward, saving time and labor costs.
- Extended Service Life: High-quality materials and design minimize wear and friction, resulting in longer operational life for both the bearing and the equipment.
- Improved Operational Efficiency: Low friction design contributes to reduced energy consumption and cooler running temperatures at high speeds.
- Versatile Application Range: An excellent choice for a wide array of industrial machinery where a non-locating bearing is required to manage radial loads and thermal growth.
