23034/W33

23034/W33 is a double-row self-aligning roller bearing with an integrated outer ring circular lubrication groove and oil hole structure. Its core function is to provide stable support with high load capacity, emphasis on the center, and long-lasting lubrication for critical rotating parts of heavy equipment in fields such as metallurgy, construction materials, mining, and ports, which require long-term continuous operation, withstand heavy impact loads, and have limited maintenance space. It is suitable for critical components such as the working rolls of rolling mills, the main shafts of grinding machines, and the eccentric shafts of crushers, where the shaft systems are prone to bending, installation alignment is difficult, and frequent shutdown maintenance is inconvenient. Its basic specifications of 170mm inner diameter, 260mm outer diameter, and 67mm width are paired with high-quality high-carbon chromium bearing steel (GCR15) for deep quenching and heat treatment, featuring excellent wear resistance and impact resistance. It can efficiently withstand extremely large radial loads and bidirectional axial loads, automatically compensate for the angle deviation between the shaft and the bearing seat, and shaft bending, and the external lubrication structure with the W33 suffix supports the continuous supply of lubricating grease by an external oiling system, significantly extending the lubrication cycle and reducing the frequency of shutdown maintenance, while balancing the multiple requirements of heavy load bearing, deviation compensation, and operational efficiency. It is the core supporting component for heavy equipment to achieve efficient, stable, and long-term operation.
