Product Overview: The NN 3018 Double Row Cylindrical Roller Bearing
The NN 3018 bearing is a high-precision, double-row cylindrical roller bearing, integral to our comprehensive NN 3000 Series within our broader Cylindrical Roller Bearings collection. With precise dimensions of 90mm bore diameter, 140mm outer diameter, and 46mm thickness, this bearing is engineered to accommodate extremely heavy radial loads and achieve high rigidity, making it suitable for demanding industrial applications. Its double-row design ensures superior load distribution and stability compared to single-row variants.
Known for their excellent performance in applications requiring high radial stiffness and precision, NN 3018 bearings feature a separable design, allowing for easier mounting and dismounting. This characteristic, combined with their robust construction, ensures prolonged operational life and consistent performance even under arduous working conditions. We are committed to supplying high-quality industrial bearings that meet rigorous industry standards, providing reliable solutions for your machinery needs. Explore our full range of NN Series bearings to find the perfect fit for your specific requirements.
