239/710X1D/C4W33X

239/710X1D/C4W33X is a large-sized self-aligning roller bearing with a special design featuring C4 large clearance and lubrication structure. Its core function is to provide a key component for medium and low-speed heavy-duty equipment that requires stable support, automatic alignment, and reliable operation guarantee, especially for those that can withstand extreme radial heavy loads, have thermal expansion / installation deviations, and have high requirements for adaptability and long-term lubrication. It compensates for shaft deflection or installation deviations through the self-aligning structure, adapts to thermal deformation and vibration with "C4" large clearance, achieves continuous lubrication with "W33" oil grooves and oil holes, and represents special design with "X1D" "X" (such as installation or load optimization, subject to manufacturer's specifications). Combined with dimensions of 710mm inner diameter, 950mm outer diameter, and 180mm width, and with dynamic load of approximately 4800kN and static load of 11700kN, it precisely fits into harsh working conditions such as mining ball mills and metallurgical rolling mills, meeting the requirements of heavy load, adaptability and long-term operation.
