Product Overview: The N 330 Cylindrical Roller Bearing
The N 330 Cylindrical Roller Bearing is a high-capacity, single-row bearing engineered for demanding industrial applications. With principal dimensions of 150x320x65mm, this bearing is part of our robust N 300 Series within the broader Cylindrical Roller Bearings category. The 'N' type design features two integral flanges on the inner ring and a flangeless outer ring. This configuration makes it a non-locating bearing, perfectly suited to accommodate axial displacement of the shaft relative to the housing in both directions, which is often caused by thermal expansion or mounting inaccuracies.
Manufactured to precision standards, the N 330 offers exceptional performance where heavy radial loads and high speeds are present. Its separable design, where the outer ring can be mounted independently of the inner ring and roller assembly, greatly simplifies installation, inspection, and maintenance procedures.
Key Features of the N 330 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement: The 'N' type design allows the shaft to move axially in both directions relative to the housing, accommodating thermal expansion.
- Separable Design: The outer ring is separable, facilitating easier and more efficient mounting and dismounting processes.
- High-Speed Performance: Engineered with an optimized internal design and cage to operate effectively at high rotational speeds with low friction.
- Robust and Durable: Constructed from high-quality, through-hardened bearing steel for enhanced durability and a long service life under tough conditions.
- High Stiffness: Provides a high degree of radial stiffness, essential for applications requiring precise shaft guidance.
Common Applications for N 330 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces common in gear systems.
- Large Electric Motors: Used as non-locating bearings to support motor shafts and manage thermal expansion during operation.
- Pumps and Compressors: Ensures stable and efficient operation of rotating components in various industrial pump and compressor models.
- Rolling Mills: Withstands the extreme loads and high-speed conditions found in steel and metal processing machinery.
- Machine Tool Spindles: Offers the rigidity and precision required for high-performance cutting and grinding operations.
- Construction and Mining Equipment: Ideal for heavy-duty machinery like excavators, conveyors, and crushers where durability is critical.
- Wind Turbines: Supports the gearbox and main shaft assemblies, handling significant and fluctuating loads.
Benefits of Using the N 330 Bearing
- Enhanced Machine Reliability: By accommodating axial shaft movement, it prevents induced axial loads, reducing stress on the bearing and adjacent components.
- Extended Service Life: The robust design and high load-carrying capacity minimize wear and extend the operational lifespan of the machinery.
- Simplified Maintenance: The separable nature of the bearing allows for straightforward inspection and replacement, reducing downtime.
- Improved Operational Efficiency: Low friction characteristics contribute to reduced energy consumption and lower operating temperatures.
- Versatile Use: Its design makes it suitable for a wide array of heavy industrial applications requiring a non-locating bearing solution.
