23052CAK/W33

23052CAK/W33 is a double-row self-aligning roller bearing with an inner diameter of 260mm, an outer diameter of 400mm, and a width of 104mm. Its core function is to provide a precise gap adjustment + high rigidity + maintenance-free grease replenishment integrated self-aligning support for the shaft systems of heavy-duty and highly impact-resistant equipment such as metallurgical rolling mills, mining crushers, cement vertical mills, port heavy-duty cranes, and large reducers. The inner ring's 1:12 conical hole allows for axial fine adjustment of the radial clearance to adapt to the thermal expansion and contraction of the shaft system and changes in working conditions. The CA type brass solid cage ensures high impact resistance and structural stability. The outer ring's W33 lubrication groove + oil injection hole enables continuous online grease replenishment, capable of compensating for ≤2° coaxiality errors. It can withstand extremely large radial loads and bidirectional axial loads, and is suitable for heavy-duty equipment scenarios with harsh working conditions and strict requirements for ease of disassembly and maintenance, as well as operational stability. It is the preferred supporting component for core shaft systems in heavy industries with high load-bearing capacity, adjustable features, impact resistance, and long-term maintenance capabilities.
