SW NU 208 Cylindrical Roller Bearing 40x80x18mm | High Load Capacity | Axial Floating Design
The SW NU 208 Cylindrical Roller Bearing is engineered for demanding industrial applications requiring exceptional radial load capacity and high-speed performance. Featuring a design where the inner ring is separable (plain) and the outer ring contains two integral flanges, the NU configuration allows for critical axial displacement (floating operation) necessary to compensate for shaft expansion or misalignment during operation. Manufactured from high-grade bearing steel (SAE 52100 equivalent), this bearing adheres to strict ISO/DIN standards, ensuring dimensional consistency and superior running accuracy, making it ideal for gearboxes, electric motors, pumps, and heavy machinery requiring robust, reliable components.
Selecting the SW NU 208 guarantees minimal maintenance downtime and optimized operational lifespan. Its optimized roller-raceway contact geometry minimizes friction and heat generation, allowing for higher limiting speeds compared to similar deep groove ball bearings. The separable design facilitates easier mounting and dismounting, streamlining maintenance processes. As a certified SW product, the NU 208 is delivered pre-lubricated with a light preservative oil, ready for installation in environments where precision and sustained heavy load resistance are paramount to operational success.
Key Features
High Radial Load Capacity: Engineered to handle significant static and dynamic radial forces common in industrial drive systems.
Axial Displacement Capability (Floating): Allows the shaft to move axially relative to the housing, preventing harmful stresses due to thermal expansion.
Separable Design: Inner and outer rings can be mounted independently, simplifying assembly and maintenance procedures.
High-Speed Performance: Optimized roller geometry and cage structure support high limiting speeds for increased operational efficiency.
SW Quality Assurance: Manufactured to stringent ISO/DIN standards for consistent quality, reliability, and precision.
