23052CA/W33

23052CA/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 high rigidity and long maintenance cycle self-aligning support for heavy-duty equipment shaft systems such as metallurgical rolling mills, mining crushers, cement vertical mills, port heavy-duty cranes, and large reducers that are subjected to heavy loads and strong impacts and have shaft systems prone to misalignment. It is equipped with a CA type brass solid cage, which is resistant to impact, wear, and has extremely strong structural stability. The outer ring features a W33 ring-shaped lubrication groove + 3 lubrication holes, enabling on-line non-stop lubrication replenishment and suitable for long-term maintenance-free conditions. It has the ability to compensate for ≤2° coaxiality error and can withstand extremely large radial loads and bidirectional axial loads. It is suitable for low to medium speed heavy-duty, harsh working conditions, and scenarios with strict requirements for bearing durability and ease of operation and maintenance. It is the preferred supporting component for the core shaft systems of heavy industrial equipment with high load-bearing capacity, resistance to impact, and ease of maintenance.
