Product Overview: The N 244 Cylindrical Roller Bearing
The N 244 is a high-capacity single-row cylindrical roller bearing designed to handle heavy radial loads in demanding industrial environments. With dimensions of 220x400x65mm, this bearing is part of our robust N Series within the broader Cylindrical Roller Bearings category. The 'N' designation signifies a specific design where the inner ring features two integral flanges, and the outer ring is flangeless. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion or potential mounting inaccuracies.
As a leading supplier of industrial components, we ensure our N 244 bearings are manufactured to the highest industry standards. Their separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation and maintenance procedures, especially in large machinery.
Key Features of the N 244 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows this bearing to support very heavy radial loads.
- Axial Displacement Accommodation: The N-type design permits free axial movement of the shaft relative to the housing in both directions, compensating for thermal expansion.
- Separable Design: The inner ring is separable from the outer ring and roller assembly, facilitating easier mounting, dismounting, and inspection.
- Low Friction Operation: Precision engineering of the rollers and raceways minimizes friction, reducing operational temperatures and energy consumption.
- High Rigidity: The robust construction provides excellent stiffness, ensuring stable and precise shaft support under heavy loads.
- Durable Construction: Manufactured from high-quality, clean bearing steel for superior durability, wear resistance, and extended service life.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale transmission systems.
- Rolling Mills: Used extensively in the steel and metalworking industries where heavy loads and high temperatures are common.
- Mining and Construction Equipment: Essential for heavy machinery such as crushers, conveyors, and excavators that operate under extreme conditions.
- Large Electric Motors and Generators: Supports rotor shafts, ensuring smooth operation and reliability in power generation.
- Pulp and Paper Machinery: Ideal for use in press rolls, calendar rolls, and other high-load sections of paper machines.
- Wind Turbines: Utilized in gearbox and main shaft applications to handle the significant radial forces generated.
- Vibrating Screens: Capable of withstanding the heavy loads and vibrations typical of screening equipment in the aggregate industry.
Benefits of Using the N 244 Bearing
- Enhanced Equipment Reliability: Its ability to handle heavy loads and accommodate axial shifts reduces stress on machinery, minimizing downtime.
- Simplified Installation and Maintenance: The separable design allows for straightforward mounting and dismounting, saving time and labor costs.
- Extended Service Life: High-quality materials and low-friction design contribute to a longer operational lifespan, even in harsh environments.
- Improved Operational Efficiency: Minimizes frictional losses, leading to better energy efficiency and cooler running temperatures.
- Versatility in Heavy-Duty Industries: Suitable for a wide range of demanding applications where standard bearings might fail prematurely.
- Prevents Damage from Thermal Expansion: Effectively manages changes in shaft length due to temperature variations, protecting the bearing and associated components.
