Product Overview: The NU 2308 Cylindrical Roller Bearing
The NU 2308 is a high-capacity single-row cylindrical roller bearing designed for demanding industrial applications. With dimensions of 40x90x33mm, this bearing is a key component in our NU 2300 Series, part of the broader Cylindrical Roller Bearings category. The NU design features two integral flanges on the outer ring and no flanges on the inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing. Its robust construction ensures reliable performance under heavy radial loads and high rotational speeds.
Key Features of the NU 2308 Bearing
- High Radial Load Capacity: Engineered with line contact between the rollers and raceways, enabling it to support significant radial forces.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation, inspection, and maintenance procedures.
- Axial Displacement Accommodation: The NU design allows for thermal expansion or contraction of the shaft, preventing induced axial loading and extending service life.
- High-Speed Performance: Optimized internal geometry and a precision cage reduce friction and heat generation, making it suitable for high-speed machinery.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional wear resistance and longevity.
- Dimensional Stability: Precision engineering ensures that the NU 2308 maintains its dimensional and running accuracy under recommended operating conditions.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy loads common in power transmission systems.
- Electric Motors: Used as a non-locating bearing on motor shafts to support radial loads while allowing for thermal expansion.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps and compressors operating under continuous, heavy-duty cycles.
- Construction and Mining Equipment: Ideal for heavy machinery like excavators, conveyors, and crushers that experience severe radial shock loads.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed spindles in lathes, mills, and grinding machines.
- Rolling Mills: Withstands the extreme loads and high temperatures found in steel and metal processing applications.
- Vibrating Screens and Shakers: The robust design is well-suited for the oscillatory motion and heavy loads in screening equipment.
Benefits of Using the NU 2308 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy radial loads reduces the risk of premature failure, leading to more reliable machinery.
- Simplified Assembly and Maintenance: The separable design allows for easier and faster mounting and dismounting, minimizing equipment downtime.
- Extended Service Life: By accommodating axial shaft movement, the bearing prevents stress and wear, resulting in a longer operational lifespan.
- Improved Operational Efficiency: The low-friction design contributes to reduced energy consumption and cooler running temperatures.
- Versatile Use: Suitable for a wide array of heavy-duty industrial applications where a non-locating bearing is required.
- Cost-Effective Solution: Its durability and low maintenance requirements translate into lower total cost of ownership over the machine's lifetime.
