Four row cylindrical roller bearings are mainstream heavy-duty rolling mill bearings, employing a separate, modular structure with a compact four-row roller arrangement for high space utilization. These bearings boast extremely high radial load capacity, sufficient rigidity, low friction coefficient, excellent limiting speed, strong operational stability, and convenient disassembly, assembly, and maintenance, with interchangeable parts. However, they can only withstand pure radial loads and cannot withstand axial forces; therefore, they require the use of a thrust bearing for positioning and limiting. They are widely applicable to the neck positions of cold and hot rolling mills, billet mills, and plate mills, suitable for the harsh metallurgical conditions of heavy loads, continuous operation, and high temperatures and dust, serving as a core transmission support component in steel rolling production lines.

First, determine the radial load based on the equipment's operating conditions, and then determine the bearing's load capacity based on the rolling mill's pressure, leaving a safety margin. Second, confirm the speed range, match the actual operating speed, and control temperature rise and limiting speed. Next, consider the operating environment, taking into account harsh conditions such as high temperature, dust, and moisture to select the appropriate seal and material type. Verify the installation space dimensions, matching the roller neck diameter, seat bore tolerances, and installation structure. Simultaneously consider the axial positioning method and match a suitable thrust bearing. Finally, consider the lubrication method, ease of disassembly and maintenance, service life, precision level, and procurement cost to comprehensively select the appropriate model, ensuring stable and long-term operation of the equipment.
