23076CAKF3/W33

23076CAKF3/W33 is a double-row self-aligning roller bearing with a 1:12 conical hole (CAK), brass solid cage (CA), F3 oil guide ring and W33 outer ring lubrication groove/oil hole. Its core function is to provide a stable support with high rigidity and strong load-bearing capacity for low-speed heavy-duty shaft systems of heavy equipment such as metallurgical rolling mills, mining crushers, cement mills, and port crane slewing mechanisms. It offers automatic self-aligning capability and is suitable for oil-lubricated long-term operation. It is particularly suitable for scenarios where the shaft system is prone to misalignment and requires efficient oil drainage and continuous oil replenishment to cope with continuous heavy-duty conditions. Its inner diameter is 380mm, outer diameter is 560mm, and width is 135mm. It is compatible with the AOH3076 disassembly sleeve (compatible with an axle diameter of 360mm). The cage and rolling elements are made of GCr15 high-carbon chromium bearing steel. The basic rated dynamic load is approximately 2570kN, and the static load is approximately 4790kN. The grease lubrication speed is approximately 630r/min, and the oil lubrication speed is approximately 800r/min. It combines the dual lubrication advantages of efficient oil drainage by F3 and convenient online oil replenishment by W33. It is compatible with heavy-duty, medium-speed equipment in industries such as metallurgy, mining, construction materials, ports, and power. It can effectively compensate for shaft deflection and installation deviations, withstand heavy loads and strong vibrations, and is suitable for continuous operation with efficient lubrication, heat dissipation, and continuous oil replenishment requirements. It is paired with the disassembly sleeve to achieve convenient assembly and disassembly and precise interference control, while balancing high reliability and operational convenience to ensure long-term stable operation of the equipment.
