23034CA/W33

23034CA/W33 is a double-row self-aligning roller bearing that integrates a brass solid cage and an oil hole structure for lubrication on the outer ring's circumferential surface. Its core function is to provide stable support with high load capacity, emphasis on the core, and long-lasting lubrication for critical rotating parts of heavy equipment in metallurgy, construction materials, mining, etc., which require long-term continuous heavy-duty operation, limited maintenance space, and high requirements for lubrication continuity. It is suitable for the working rolls of rolling mills, the main shafts of grinding machines, and the eccentric shafts of crushers, etc., which have flexible shafts, difficult installation alignment, and inconvenient frequent maintenance. 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. The CA-type brass cage enhances the roller's guiding accuracy and load distribution uniformity, suitable for medium-high speed heavy-duty scenarios. The outer ring lubrication structure with the W33 suffix supports continuous lubricant supply from an external oil injection system, significantly extending the lubrication cycle, reducing the frequency of shutdown maintenance, and balancing multiple requirements such as heavy load bearing, deviation compensation, and operational efficiency. It is the core supporting component for heavy equipment to achieve efficient and stable long-term operation.
