23032/W33

23032/W33 is a double-row self-aligning roller bearing with an outer ring lubrication groove and oil holes structure. Its core function is to provide stable rotational support for large heavy-duty equipment in the metallurgy, mining, and papermaking industries that require long-term continuous operation and are not convenient for frequent shutdown maintenance. It offers a combination of high load capacity, emphasis on core stability and long-term lubrication guarantee, suitable for harsh working conditions where shaft systems are prone to bending deformation, installation is not coaxial, and lubrication supply conditions are limited. This bearing maintains a basic specification of 160mm inner diameter, 240mm outer diameter, and 60mm width. Based on the classic structure of double-row rollers and spherical outer ring raceways, it can automatically compensate for the coaxiality deviation during equipment operation, stably withstand extremely large radial loads and bidirectional axial loads, perform reliably when subjected to vibration and impact loads, and the suffix W33 corresponds to the outer ring circular oil groove and evenly distributed oil holes design, which supports continuous lubricant replenishment through an external oil injection device, effectively extending the lubrication cycle of the bearing, reducing wear, overheating faults caused by insufficient lubrication, and lowering the frequency of equipment shutdown maintenance. It is made of high-quality high-carbon chromium bearing steel and undergoes professional quenching and heat treatment, featuring excellent wear resistance and fatigue resistance. It is widely suitable for equipment such as metallurgical rolling machine frames rollers, mining cone crushers main shafts, paper machinery roller systems, heavy compressors, etc., balancing the dual needs of equipment stable operation and maintenance cost control.
