Product Overview: The N 238 Cylindrical Roller Bearing
The N 238 Cylindrical Roller Bearing is a high-capacity, single-row bearing engineered for demanding industrial applications requiring robust radial support. With key dimensions of 190x340x55mm, this component is a vital part of our N 200 Series within the broader Cylindrical Roller Bearings category. The 'N' design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions where thermal expansion or mounting inaccuracies are a concern.
Manufactured from high-quality bearing steel, the N 238 is designed for high radial loads and high-speed operation. Its separable design—where the outer ring can be mounted independently from the inner ring and roller assembly—simplifies both installation and maintenance procedures. This bearing is a reliable choice for heavy machinery where performance and durability are critical.
Key Features of the N 238 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The flangeless outer ring allows for free axial movement in both directions, compensating for thermal expansion of the shaft.
- Separable Design: The inner ring with the roller and cage assembly can be mounted separately from the outer ring, facilitating easier installation and inspection.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from premium-grade bearing steel for superior strength, durability, and resistance to wear and fatigue.
- Dimensional Stability: Precision manufacturing ensures tight tolerances for reliable and consistent performance under load.
Common Applications of N 238 Bearings
- Industrial Gearboxes: Provides strong support for gears and shafts, handling the high radial forces common in power transmission systems.
- Large Electric Motors: Used as non-locating bearings to support motor shafts while allowing for thermal expansion.
- Construction and Mining Equipment: Essential in heavy machinery such as excavators, loaders, and crushing equipment where loads are extreme.
- Rolling Mills: Withstands the heavy radial loads and high temperatures found in steel and metal processing machinery.
- Pumps and Compressors: Ensures the stable and efficient rotation of shafts in large-scale industrial fluid handling systems.
- Wind Turbines: Supports main shafts and gearboxes, providing reliability in renewable energy generation.
- Vibrating Screens and Shakers: Its robust design is well-suited for the harsh, high-vibration environments of material processing.
Benefits of Using the N 238 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy loads and axial displacement reduces stress on associated components, minimizing downtime.
- Simplified Assembly and Maintenance: The separable nature of the bearing allows for straightforward mounting and dismounting, saving time and labor costs.
- Extended Service Life: The durable materials and low-friction design contribute to a long operational life, even in harsh conditions.
- Improved Operational Efficiency: Minimizes friction and heat, leading to better energy efficiency and smoother machine performance.
- Prevents premature failure: By accommodating shaft expansion, it prevents the buildup of internal stresses that can lead to bearing damage.
- Versatile Performance: A reliable solution for a wide array of heavy industrial machinery. For alternative configurations, consider the NU 238 or NJ 238.
