Product Overview: The NU 2226 Cylindrical Roller Bearing
The NU 2226 is a high-capacity single-row cylindrical roller bearing with dimensions of 130x230x40mm. As a key component in our Cylindrical Roller Bearings range, this model is part of the versatile NU Series and the heavy-duty NU 2200 Series. Its distinctive NU design features two integral flanges on the outer ring and no flanges on the inner ring. This configuration is engineered to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured to precise industry standards, the NU 2226 is designed for applications demanding high radial load capacity and high-speed operation. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures. This bearing is a reliable choice for heavy industrial equipment where durability and performance are paramount.
Key Features of the NU 2226 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows the bearing to support heavy radial loads.
- Axial Displacement Accommodation: The NU design with a flangeless inner ring permits free axial movement, compensating for thermal expansion or shaft deflection.
- Separable Design: The inner and outer rings can be separated, facilitating easier mounting and dismounting processes.
- High-Speed Performance: Engineered with an optimized internal design and cage to minimize friction and heat, making it suitable for high rotational speeds.
- Robust and Durable: Constructed from high-quality, clean bearing steel to ensure a long operational life even in demanding conditions.
- Interchangeability: Components are dimensionally standardized, allowing for interchangeability with other manufacturers' parts.
Common Applications of NU 2226 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy radial forces common in gear systems.
- Pumps and Compressors: Used in large industrial pumps where high loads and speeds are present.
- Electric Motors and Generators: Ideal as a non-locating bearing on the drive end of large electric motors.
- Rolling Mills: Withstands the extreme radial loads found in steel and metal processing machinery.
- Construction and Mining Equipment: Essential in heavy machinery like excavators, crushers, and conveyors.
- Wind Turbines: Utilized in gearbox and main shaft applications due to its high load-carrying capabilities.
- Machine Tool Spindles: Offers the precision and rigidity required for high-performance machine tools.
Benefits of Using the NU 2226 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy radial loads and accommodate axial shifts reduces stress on other components, preventing premature failures.
- Simplified Maintenance: The separable nature of the bearing allows for straightforward inspection, lubrication, and replacement, reducing downtime.
- Extended Service Life: Low friction and high durability lead to a longer operational lifespan for both the bearing and the machinery.
- Improved Operational Efficiency: Minimized friction reduces energy loss and heat generation, contributing to more efficient machine performance.
- Versatile Mounting Options: The ability to mount components separately provides flexibility in assembly, especially in tight or complex arrangements.
- Cost-Effective Solution: Offers a durable and reliable performance that minimizes the need for frequent replacements and costly maintenance.
