Product Overview: The NU 2218 Cylindrical Roller Bearing
The NU 2218 bearing is a high-capacity, single-row cylindrical roller bearing with dimensions of 90x160x40mm. As a key component in our Cylindrical Roller Bearings range, this bearing is part of the versatile NU 2200 Series. Its NU design features two flanges on the outer ring and a flangeless inner ring. This configuration is engineered to accommodate heavy radial loads and high speeds, while also allowing for axial displacement of the shaft relative to the housing in both directions. The separable nature of the inner and outer rings simplifies mounting and dismounting procedures, making it a practical choice for a wide array of industrial applications.
Features of the NU 2218 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Separable Design: The inner ring can be mounted independently of the outer ring and roller assembly, simplifying installation and maintenance.
- Axial Displacement: The NU design allows the shaft to move axially in relation to the housing, compensating for thermal expansion or mounting inaccuracies.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, making it suitable for high-speed operations.
- Robust and Durable: Manufactured from high-quality bearing steel to ensure long service life even under demanding conditions.
- Interchangeability: Produced to strict industry standards, ensuring dimensional and running accuracy for easy replacement.
