23030KF3

The 23030KF3 is a self-aligning roller bearing designed for heavy-duty and complex working conditions. Its core function is to provide rotating support for heavy equipment in fields such as metallurgy, mining, and construction materials, featuring both flexible assembly and stable load-bearing capacity. It is suitable for environments with installation deviations and strong vibrations, and also meets the installation requirements of specific component pairs. This bearing continues the basic specifications of the 23030 series, with an inner diameter of 150mm, an outer diameter of 225mm, and a width of 56mm. The suffix K indicates a conical hole with a 1:12 taper, which can be flexibly assembled on a cylindrical shaft using a locking sleeve or release sleeve, facilitating later disassembly and fine adjustment of the radial clearance. The suffix F3 corresponds to specific characteristics that enable it to match the corresponding old model 113620W2 components, ensuring compatibility with some older equipment or specific customized equipment, thereby reducing the adaptation cost during equipment component replacement. It possesses the classic advantages of a self-aligning roller bearing, with a dual-row roller and spherical outer raceway structure that can automatically compensate for the deflection deformation and installation deviations during the rotation of the shaft system, avoiding additional stress damage to the bearing. It can stably withstand extremely large radial loads and certain bidirectional axial loads. The material mostly uses high-quality high-carbon chromium bearing steel, which has excellent wear resistance and fatigue resistance after quenching and heat treatment. The basic rated dynamic load is approximately 437kN, and the basic rated static load is approximately 750kN. The grease lubrication limit speed can reach 1700r/min, and the oil lubrication limit speed can reach 2200r/min. It is widely applicable to heavy machinery such as mine crushers, metallurgical conveyor belts, and cement mills, and can also be adapted to some equipment that needs to be compatible with specific old components, ensuring the long-term stable operation of the equipment under various working conditions.
