Product Overview: The NUP 208 Cylindrical Roller Bearing
The NUP 208 bearing is a high-performance single-row cylindrical roller bearing, engineered to manage substantial radial loads while providing precise axial shaft location in both directions. With principal dimensions of 40x80x18mm, this bearing is a key component in our NUP 200 Series, which is part of the extensive Cylindrical Roller Bearings family. The 'NUP' designation signifies a unique design with two integral flanges on the outer ring and a single integral flange plus a loose flange ring on the inner ring. This configuration effectively constrains the shaft axially, making it ideal for fixed-end bearing applications.
As a specialist supplier of industrial components, we ensure our NUP 208 bearings are manufactured to rigorous standards. The line contact between the rollers and raceways minimizes edge stresses, allowing for superior performance under heavy radial loads and at high rotational speeds. This bearing's separable design simplifies mounting and dismounting, which is a significant advantage during installation and maintenance procedures.
Features of the NUP 208 Bearing
- Bi-Directional Axial Location: Designed to locate the shaft axially in both directions, making it an excellent choice for fixed-end applications.
- High Radial Load Capacity: The cylindrical rollers and raceways provide a large contact area, enabling the bearing to support heavy radial forces.
- Separable Design: The inner ring, outer ring, and roller assembly can be mounted independently, facilitating easier installation and maintenance.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, allowing for reliable operation at high speeds.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life.
- Line Contact Geometry: Reduces stress concentrations at the roller ends, enhancing performance and reliability under load.
Applications of NUP 208 Bearings
- Industrial Gearboxes: Provides rigid support and precise positioning for gears and shafts in transmission systems.
- Electric Motors: Used as a locating bearing on motor shafts to handle radial loads and control axial movement.
- Pumps and Compressors: Ensures the stable and efficient operation of rotating assemblies in fluid machinery.
- Machine Tool Spindles: Offers the rigidity and precision required for high-accuracy machining applications.
- Construction and Mining Equipment: Withstands the heavy loads and harsh operating conditions found in heavy machinery.
- Vibrating Screens and Shakers: Its robust design is well-suited for applications involving significant vibration and shock loads.
- Automotive Transmissions: Delivers reliable performance in demanding automotive powertrain applications.
Benefits of Using the NUP 208 Bearing
- Enhanced Shaft Stability: Provides precise and rigid axial positioning, improving the overall stability and accuracy of the machinery.
- Increased Equipment Reliability: The high load-carrying capacity prevents premature failure, leading to less downtime and more reliable operation.
- Simplified Assembly: The separable nature of the bearing components streamlines the mounting and dismounting process, saving time and effort.
- Extended Service Life: High-quality materials and optimized internal design contribute to a long and trouble-free operational life.
- Improved Operational Efficiency: Low-friction characteristics help to reduce energy consumption and minimize heat generation during operation.
- Versatile Locating Solution: A single NUP bearing can often replace a combination of other bearings used for radial support and axial location, simplifying the design. Other common cylindrical roller bearing configurations include the NU 208 for free axial movement and the NJ 208 for single-direction location.
