Product Overview: The NN 3018 Double-Row Cylindrical Roller Bearing
The NN 3018 is a high-precision, double-row cylindrical roller bearing designed for applications demanding exceptional radial stiffness and high load-carrying capacity. With dimensions of 90x140x37mm, this bearing is a crucial component in machinery where precision and rigidity are paramount. As part of our extensive Cylindrical Roller Bearings collection, the NN 3018 belongs to the NN 3000 Series, known for its suitability in high-speed and high-accuracy environments, such as machine tool spindles.
The unique design of the NN 3018 features two rows of cylindrical rollers, providing superior radial load support and minimal deformation under load. Its separable construction, with a flanged inner ring and a flangeless outer ring, allows the shaft to displace axially relative to the housing. This feature simplifies mounting and dismounting procedures, making it a practical choice for complex assemblies. As a leading supplier of industrial components, we ensure our NN 3018 bearings meet stringent industry standards for reliable and long-lasting performance.
Features of the NN 3018 Bearing
- High Radial Load Capacity: The double-row design distributes loads effectively, making it ideal for heavy radial force applications.
- Exceptional Rigidity: Engineered to provide high stiffness, minimizing deflection and ensuring rotational accuracy.
- High-Speed Performance: Low-friction design characteristics enable smooth operation at high rotational speeds.
- Separable Design: The inner ring, with its roller and cage assembly, can be mounted independently of the outer ring, simplifying installation and maintenance.
- Axial Displacement: Accommodates thermal expansion or contraction of the shaft by allowing free axial movement within the bearing.
