Product Overview: The NU 308 Cylindrical Roller Bearing
The NU 308 bearing is a robust and high-performance component within our NU 300 Series of Cylindrical Roller Bearings. This bearing is specifically designed with two integral flanges on its outer ring and a smooth inner ring, making it ideal for applications where axial displacement between the shaft and the housing needs to be accommodated without constraint. With precise dimensions of 40mm bore diameter, 90mm outer diameter, and 23mm thickness, the NU 308 is engineered to manage high radial loads and operate effectively at high speeds.
As a trusted supplier of industrial bearings and mechanical parts, we ensure that our NU 308 bearings are manufactured to rigorous industry standards. Their separable components (outer ring with rollers and cage assembly, and inner ring) facilitate easier mounting and dismounting, which is a significant advantage in maintenance and assembly processes. This type of bearing is critical in machinery requiring strong radial support and operational flexibility under varying thermal expansion conditions. Explore our comprehensive range of cylindrical roller bearings to find the optimal solution for your industrial requirements.
Key Features of the NU 308 Bearing
- High Radial Load Capacity: Designed with a large contact area between rollers and raceways, enabling it to withstand substantial radial forces.
- High-Speed Capability: Precision manufacturing and roller design allow for efficient operation at elevated rotational speeds.
- Separable Components: The inner ring is detachable from the outer ring and roller assembly, simplifying installation and maintenance.
- Axial Displacement Accommodation: The NU configuration allows for axial movement of the shaft relative to the housing, preventing axial loads from being imposed on the bearing due to thermal expansion.
- Low Friction: Optimized roller-raceway geometry contributes to minimized friction and reduced heat generation during operation.
- Durable Construction: Crafted from high-quality bearing steel to ensure exceptional wear resistance and extended service life in demanding industrial environments.
