The outer ring of NN type cylindrical roller bearing has no ribs, and the inner ring has ribs on both sides of the inner ring. And there is a middle rib in the middle. Can allow the shaft relative to the bearing seat to produce axial displacement in two directions. NN3020 Cylindrical Roller Bearing Features High carrying capacity Due to its second row of rollers, double row cylindrical roller bearings are suitable for larger radial loads. Low friction (roller end face / rib contact area) The open rib design, as well as the roller end design and surface finish, promote lubricating oil film, thereby reducing friction and bringing a higher basic load rating. Long-lasting The logarithmic curve profile reduces the edge stress at the roller/raceway contact and reduces the sensitivity to misalignment and shaft deflection. Improve operational reliability The surface treatment of the contact surface between the roller and the raceway facilitates the formation of a hydrodynamic lubricant film. Separable and interchangeable The separate components of double row cylindrical roller bearings are interchangeable. This is convenient for installation, disassembly, and maintenance inspection. High-speed capability The cage design is suitable for high speed, rapid acceleration, and highest load.
