NN 3022 KTN9/SP

The NN 3022 KTN9/SP Super-Precision Bearing is a high-performance, double-row cylindrical roller bearing meticulously engineered for applications demanding extreme accuracy, rigidity, and high-speed capability. This specific designation highlights its advanced features: "NN" denotes a double-row cylindrical roller bearing design, optimized for superior radial load capacity. The "3022" refers to its specific size series, while "KTN9" typically indicates a high-performance polyamide cage that contributes to lower friction, reduced heat generation, and quieter operation, especially beneficial at high rotational speeds.

Crucially, the "SP" suffix signifies its super-precision class, meaning it's manufactured to exceptionally tight tolerances (often P4 or higher according to ISO standards), ensuring minimal runout, vibration, and excellent running accuracy. The design, usually with an inner ring without flanges and an outer ring with three integral flanges, allows for essential axial displacement between the inner and outer rings, simplifying mounting in certain setups. Primarily found in critical machinery such as machine tool spindles (for milling, grinding, and turning), precision printing presses, high-speed gearboxes, and other high-precision rotating equipment, the NN 3022 KTN9/SP delivers unparalleled performance, directly translating to superior machining quality, enhanced component lifespan, and improved overall productivity in demanding industrial environments.
