Product Overview: The NU 414 Cylindrical Roller Bearing
The NU 414 is a high-capacity single-row cylindrical roller bearing designed to handle demanding industrial applications. With dimensions of 70x180x42mm, this bearing is a key component in our NU 400 Series, part of the broader Cylindrical Roller Bearings category. The NU design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an ideal choice for non-locating bearing positions.
Manufactured to precise standards from high-quality bearing steel, the NU 414 is engineered for high radial load capacity and high-speed performance. Its separable design—where the outer ring can be mounted independently of the inner ring and roller assembly—greatly simplifies installation and maintenance procedures. This bearing is essential for machinery where thermal expansion or contraction of the shaft must be managed without inducing axial stress.
Key Features of the NU 414 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent support 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 Components: The inner and outer rings can be mounted separately, simplifying the installation and dismounting process.
- High-Speed Performance: Engineered with an optimized internal geometry to minimize friction and support high rotational speeds.
- Robust Construction: Made from premium-grade, through-hardened bearing steel for exceptional durability and long service life.
- Interchangeability: Manufactured to industry-standard dimensions, ensuring it can be easily interchanged with equivalent bearings.
