Product Overview: The NU 2207 Cylindrical Roller Bearing
The NU 2207 is a high-performance single-row cylindrical roller bearing, an essential component for applications demanding high radial load capacity and the ability to accommodate axial displacement. With principal dimensions of 35mm bore diameter, 72mm outer diameter, and 23mm thickness, this bearing is part of our robust NU 2200 Series. The "NU" designation signifies a design where the inner ring is separable and has no flanges, while the outer ring features two integral flanges. This configuration allows the shaft to move axially in either direction relative to the housing, making it ideal for use as a non-locating bearing.
As a key part of our Cylindrical Roller Bearings collection, the NU 2207 is manufactured to precise standards using high-quality bearing steel. Its design ensures low friction and long service life, even in demanding industrial environments. This bearing is crucial for the reliable operation of heavy machinery where thermal expansion or mounting inaccuracies can cause shaft movement.
Key Features of the NU 2207 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The separable inner ring without flanges allows for axial movement of the shaft, compensating for thermal expansion.
- Separable Design: The inner and outer rings can be mounted independently, which simplifies the installation, inspection, and maintenance processes.
- High-Speed Performance: Engineered with a robust cage and optimized internal geometry to support high rotational speeds.
- Durable Construction: Manufactured from premium-grade, through-hardened bearing steel for maximum wear resistance and longevity.
- Low Friction Operation: Precision engineering minimizes frictional torque, reducing heat generation and improving operational efficiency.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces typical in transmission systems.
- Electric Motors: Used as a non-locating bearing on motor shafts to support heavy loads and allow for thermal expansion.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps and compressors under continuous operation.
- Construction and Mining Equipment: Ideal for heavy-duty machinery like excavators, conveyors, and crushers that operate in harsh conditions.
