Product Overview: The NU 208 Cylindrical Roller Bearing
The NU 208 is a high-capacity single-row cylindrical roller bearing with dimensions of 40x80x18mm. As a key component in our Cylindrical Roller Bearings category, it is specifically designed to handle very high radial loads at high speeds. This bearing is part of the versatile NU 200 Series, known for its separable design. The NU designation means the outer ring has two integral flanges while the inner ring is flangeless. This unique construction allows the shaft to move axially relative to the housing in both directions, making it ideal for use as a non-locating bearing that accommodates thermal expansion or shaft deflection.
As a leading supplier of industrial components, we ensure our NU 208 bearings are manufactured to the highest industry standards, providing excellent reliability and service life in demanding applications such as gearboxes, pumps, and electric motors.
Key Features of the NU 208 Bearing
- Separable Design: The inner ring can be removed from the outer ring and roller assembly, simplifying the mounting and dismounting process.
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of heavy radial forces.
- Axial Displacement Accommodation: The flangeless inner ring design permits axial movement of the shaft in either direction relative to the housing.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-rotational speed applications.
- Robust Construction: Manufactured from high-quality, through-hardened bearing steel for superior durability and wear resistance.
- Interchangeability: Produced to standard dimensions, allowing for easy replacement and interchangeability with other standard bearings.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in power transmission.
- Electric Motors: Used as a non-locating bearing on motor shafts to support radial loads while allowing for thermal expansion.
- Pumps and Compressors: Ensures reliable operation of rotating components under heavy radial stress.
- Construction and Mining Equipment: Ideal for heavy-duty machinery where high radial loads are prevalent.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed machining applications.
