Product Overview: The NN 3019 Double-Row Cylindrical Roller Bearing
The NN 3019 is a high-precision double-row cylindrical roller bearing engineered for applications demanding exceptional rigidity and high radial load-carrying capacity. With dimensions of 95x145x36mm, this bearing is a key component in our NN 3000 Series line of Cylindrical Roller Bearings. Its design features two rows of cylindrical rollers, which provides excellent support for rotating shafts, minimizing deflection even under heavy loads. This makes it particularly well-suited for high-speed, high-accuracy machinery.
As a specialist in industrial mechanical parts, we ensure our NN 3019 bearings meet stringent industry standards for performance and durability. The bearing's inner ring has three integral flanges, while the outer ring is flangeless, allowing the bearing to accommodate axial displacement of the shaft relative to the housing in both directions. This feature, combined with its separable design, facilitates easier mounting and maintenance. Explore our complete range of NN Series bearings to find the optimal solution for your high-performance applications.
Features of the NN 3019 Bearing
