Product Overview: The NU 305 Cylindrical Roller Bearing
The NU 305 bearing is a high-performance cylindrical roller bearing with dimensions of 25x62x17mm, engineered to handle high radial loads at high speeds. As a key component in our NU 300 Series, this bearing is part of the broader Cylindrical Roller Bearings category. Its distinctive 'NU' design features two flanges on the outer ring and a smooth, flangeless inner ring. This configuration allows the inner ring to move axially relative to the outer ring, making it ideal for accommodating thermal expansion and contraction of the shaft.
The separable design of the NU 305, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures. Manufactured from premium-grade bearing steel, it provides exceptional durability and reliable performance in demanding industrial environments. This bearing is a preferred choice for applications where robust radial support and axial freedom are essential.
Key Features of the NU 305 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows it to support heavy radial loads.
- Separable Inner Ring: The inner ring can be removed, facilitating easy mounting and dismounting of the bearing.
- Axial Displacement Accommodation: The NU design allows for axial movement between the shaft and housing, compensating for thermal expansion.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from high-quality, hardened bearing steel for enhanced wear resistance and longevity.
- Dimensional Stability: Precision manufacturing ensures consistent dimensions for reliable and interchangeable use.
