Product Overview: The NN 3024 Double-Row Cylindrical Roller Bearing
The NN 3024 is a high-precision, double-row cylindrical roller bearing with dimensions of 120x180x46mm. As a key component in our NN 3000 Series, this bearing is engineered for applications demanding exceptional radial stiffness and high load-carrying capacity. Part of the broader Cylindrical Roller Bearings family, its design features two rows of cylindrical rollers, making it ideal for machine tool spindles and other precision machinery where minimal shaft deflection is critical. The inner ring has three flanges, while the outer ring is flangeless, allowing for axial displacement of the shaft relative to the housing.
As a leading supplier of industrial components, we ensure our NN 3024 bearings are manufactured to the highest industry standards, providing unparalleled reliability and performance. This bearing is designed to be separable, meaning the outer ring can be mounted independently of the inner ring and roller assembly, which greatly simplifies installation and maintenance procedures.
Key Features of the NN 3024 Bearing
- High Radial Load Capacity: The double-row roller design provides excellent support for heavy radial loads.
- Exceptional Rigidity: Engineered to minimize deflection under load, ensuring high rotational accuracy, which is essential for precision applications.
- Separable Design: The inner and outer rings can be mounted separately, simplifying the assembly and dismounting process.
