Product Overview: The NU 212 Cylindrical Roller Bearing
The NU 212 Cylindrical Roller Bearing is a robust and highly efficient component, specifically designed for applications requiring exceptional radial load capacity and high-speed performance. As a key part of our extensive NU 200 Series Cylindrical Roller Bearings, this bearing features a 60 mm bore diameter, 110 mm outer diameter, and 22 mm thickness. The "NU" designation indicates a specific configuration where the outer ring has two integral flanges, while the inner ring is smooth and unflanged. This design allows for axial displacement of the shaft relative to the housing within the bearing itself, making it particularly suitable for applications where thermal expansion or contraction of the shaft must be accommodated without inducing axial stress on the bearing. Our NU 212 bearings are manufactured to stringent industry standards, ensuring reliable and long-lasting operation in the most demanding industrial environments.
Key Features of the NU 212 Bearing
- High Radial Load Capacity: Designed with rollers that have a larger contact area with the raceways, enabling it to withstand significant radial forces.
- High-Speed Capability: Precision-engineered components and optimized internal geometry allow for efficient operation at high rotational speeds.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance procedures.
- Axial Displacement Accommodation: The unflanged inner ring allows for relative axial movement between the shaft and housing, preventing stress from thermal expansion.
- Low Friction: Optimized roller-raceway contact and precision manufacturing contribute to reduced friction, minimizing heat generation and energy loss.
- Exceptional Rigidity: Provides excellent stiffness, crucial for maintaining precise shaft positioning and operational accuracy.
- Durable Construction: Manufactured from high-quality bearing steel for superior wear resistance and extended service life.
