Product Overview: The NU 211 Cylindrical Roller Bearing
The NU 211 is a single-row cylindrical roller bearing designed for high performance in demanding industrial applications. With principal dimensions of 55mm Bore Diameter, 100mm Outer Diameter, and 21mm Thickness, this bearing is a key component in our Cylindrical Roller Bearings collection. The NU design is distinguished by its two integral flanges on the outer ring and a smooth, flangeless inner ring. 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.
As a leading supplier of industrial components, we provide NU 211 bearings manufactured to the highest standards, ensuring exceptional radial load capacity and suitability for high-speed operation. This bearing is part of the versatile NU 200 Series, known for its robust construction and reliability. Explore our full range of NU Series bearings to find the perfect solution for your machinery needs.
Key Features of the NU 211 Bearing
- Axial Displacement: The separable inner ring design allows for axial movement of the shaft relative to the housing, compensating for thermal expansion.
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed applications.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability and a long operational lifespan.
- Interchangeability: Produced to standard dimensions, allowing for easy interchangeability with other manufacturers' parts.
