Product Overview: The NU 320 Cylindrical Roller Bearing
The NU 320 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 100mm bore diameter, 215mm outer diameter, and 47mm thickness, this bearing is a key component in our NU 300 Series lineup. The NU design features two integral flanges on the outer ring and a flangeless inner ring, which allows for axial displacement of the shaft relative to the housing in both directions. This makes the NU 320 an excellent choice for use as a non-locating bearing, accommodating thermal expansion or contraction of the shaft. Manufactured from high-quality bearing steel, it provides exceptional performance where heavy radial loads and high speeds are present.

Features of the NU 320 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial loads.
- Axial Displacement: The NU design accommodates axial movement of the shaft, preventing stress from thermal expansion.
- Separable Design: The inner ring can be removed from the outer ring and roller assembly, simplifying mounting and dismounting procedures.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from premium-grade bearing steel for enhanced durability, wear resistance, and a long service life.
- High Stiffness: Provides excellent radial rigidity, ensuring stable and precise operation under load.
