23034CAK/W33

23034CAK/W33 is a double-row self-aligning roller bearing that integrates a brass solid cage, a 1:12 taper conical hole, and an external ring circumferential lubrication groove oil hole structure. Its core function is to provide stable support with high load capacity, emphasis on the center, convenient assembly, and long-lasting lubrication for critical rotating parts of heavy equipment in the metallurgy, mining, and construction materials industries that require frequent disassembly and maintenance, long-term heavy-load continuous operation, and high lubrication continuity. It is suitable for applications such as rolling mill working rolls, mill shafts, and eccentric shafts of crushers, where the shaft systems are prone to bending, have difficult installation and alignment, and are inconvenient for frequent shutdown. Its basic specifications of 170mm inner diameter, 260mm outer diameter, and 67mm width are paired with high-quality high-carbon chromium bearing steel (GCR15) deep quenching and heat treatment material. It has excellent wear resistance and impact resistance, and can efficiently withstand extremely large radial loads and bidirectional axial loads. The CA type brass cage enhances the roller guiding accuracy and load distribution uniformity, suitable for medium-high speed heavy-load scenarios. The K suffix conical hole is combined with a locking sleeve to achieve quick assembly and disassembly of the bearing and fine adjustment of the clearance, and the W33 outer ring lubrication structure supports continuous lubricant supply from an external oiling system, significantly extending the lubrication cycle and shortening maintenance time. It also balances multiple requirements such as heavy-load bearing, deviation compensation, convenient assembly, and efficient operation and maintenance, and is the core supporting component for heavy equipment to achieve stable and efficient long-term operation.
