Product Overview: The NU 206 Cylindrical Roller Bearing
The NU 206 bearing is a high-performance cylindrical roller bearing with principal dimensions of 30x62x16mm. As a key component in our Cylindrical Roller Bearings range and a part of the NU 200 Series, this bearing is engineered to handle high radial loads at high speeds. The 'NU' 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 use as a non-locating bearing.
Manufactured from high-quality bearing steel, the NU 206 ensures durability and reliability in demanding industrial environments. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation, inspection, and maintenance procedures. This bearing is a fundamental part for machinery requiring robust radial support and thermal expansion management.
Key Features of the NU 206 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement: The NU design allows for free axial movement of the shaft in relation to the housing, compensating for thermal expansion or mounting errors.
- Separable Design: The inner ring is separable from the outer ring and roller cage assembly, which facilitates easier mounting and dismounting.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed applications.
- Robust Construction: Made from premium-grade steel for superior wear resistance and extended operational life.
- Interchangeability: Manufactured to standardized dimensions, allowing for easy replacement and interchangeability with other brands.
Common Applications of NU 206 Bearings
