The SKF NK3030TN is a high-performance genuine SKF needle roller bearing without an inner ring, designed for applications where the shaft can be induction hardened and ground to serve as the inner raceway. This robust bearing features a 30 mm bore diameter (raceway diameter Fw), a 40 mm outer diameter (D), and a 30 mm width (B). With a basic dynamic load rating of 27.5 kN and a static load rating of 38 kN, it offers high load-carrying capacity and rigidity. The 'TN' suffix indicates a plastic cage, contributing to its operational efficiency and limiting speeds of up to 11,000 rpm with grease lubrication or 16,000 rpm with oil lubrication. Its compact design is ideal for space-constrained machinery requiring reliable radial support.
