Product Overview: The NU 332 Cylindrical Roller Bearing
The NU 332 is a single-row cylindrical roller bearing engineered for heavy-duty industrial applications requiring high radial load capacity. With principal dimensions of 160mm bore diameter, 340mm outer diameter, and 68mm thickness, this bearing is a robust component in our NU 300 Series lineup. The NU design features two flanges on the outer ring and a flangeless inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions, particularly where thermal expansion of the shaft is a factor.
Manufactured to precision standards from high-grade bearing steel, the NU 332 ensures reliability and a long service life in demanding environments. As a key part of our Cylindrical Roller Bearings collection, it provides a dependable solution for machinery across various sectors. The separable design, with a removable inner ring, simplifies both the mounting and dismounting processes, reducing maintenance time and complexity.
Key Features of the NU 332 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement of the shaft in relation to the housing, compensating for thermal expansion.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance.
- High-Speed Capability: Engineered with low-friction characteristics, making it suitable for high-speed rotational applications.
- Robust Construction: Made from premium-quality, clean bearing steel for maximum durability and resistance to wear and fatigue.
- Dimensional Stability: Precision manufacturing ensures consistent performance and interchangeability.
Common Applications of NU 332 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts under heavy loads and high speeds.
- Electric Motors: Used as non-locating bearings in large industrial motors to handle shaft expansion.
- Pumps and Compressors: Ensures smooth and efficient operation in heavy-duty fluid and gas handling equipment.
- Construction Machinery: Found in the transmissions and final drives of heavy equipment like excavators and loaders.
- Mining and Quarrying Equipment: Ideal for crushers, vibrating screens, and conveyor systems that operate under extreme conditions.
- Steel and Metal Rolling Mills: Withstands the heavy loads and high temperatures common in rolling mill applications.
- Wind Turbines: Used in the gearboxes of wind energy systems to support high radial forces.
Benefits of Using the NU 332 Bearing
