Product Overview: The NN 3052 Double-Row Cylindrical Roller Bearing
The NN 3052 is a high-precision, double-row cylindrical roller bearing with dimensions of 260x400x104mm. As a key component in our NN 3000 Series, this bearing is engineered to handle extremely high radial loads and operate at high speeds, making it an ideal choice for applications requiring exceptional rigidity and rotational accuracy. The NN design features two rows of cylindrical rollers and is part of the broader Cylindrical Roller Bearings family. Its inner ring is separable, which simplifies the mounting and dismounting process. This bearing is designed to accommodate radial loads exclusively and is not suitable for axial forces.
Key Features of the NN 3052 Bearing
- High Radial Load Capacity: The double-row roller design provides a large contact area, enabling it to support very heavy radial loads.
- High Rigidity: Its robust construction offers excellent stiffness, which is crucial for precision applications like machine tool spindles.
- High-Speed Performance: Engineered with low-friction geometry, allowing for reliable operation at high rotational speeds.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, facilitating easier installation and maintenance.
- Precision Manufacturing: Produced to tight tolerances to ensure high running accuracy and consistent performance.
- Durable Construction: Manufactured from high-quality, hardened bearing steel for superior durability and a long service life under demanding conditions.
