23048CF3

23048CF3 is a double-row self-aligning roller bearing with an inner diameter of 240mm, an outer diameter of 360mm, and a width of 92mm. Its core function is to provide a highly reliable main support for cylindrical hole shaft systems of heavy-duty, highly-vibratory and installation-offset large-scale equipment such as metallurgical rolling mills, mining crushers, cement vertical mills, heavy-duty reducers, and port cranes. The suffix "CF3" indicates that the outer ring is coated with anti-corrosion material, which can effectively resist slight corrosive media erosion to extend the service life of the bearing in harsh environments. The C-type symmetrical spherical rollers are paired with copper alloy machined cages, providing strong shock absorption and vibration resistance, suitable for high-frequency vibration and heavy-duty working conditions. The cylindrical hole design is suitable for shafts with shoulder installation, ensuring stable assembly and compatibility with different interference fits to meet the requirements of the working conditions. It can compensate for ≤2° of installation offset and shaft deflection, and has bidirectional axial bearing capacity. The material is GCr15 high-carbon chromium bearing steel, which undergoes deep quenching and heat treatment to HRC60-64. It is wear-resistant and fatigue-resistant, with a basic rated dynamic load of approximately 1160kN and a static load of approximately 2140kN. The grease lubrication limit speed is approximately 530-550r/min, and the oil lubrication is approximately 670-700r/min. The actual usage recommendation is to control the speed within 70% of the limit to reduce temperature rise, meeting the dual requirements of long-term continuous stable operation of the equipment under complex working conditions and reducing maintenance costs.
