23052F3

23052F3 is a double-row self-aligning roller bearing (cylindrical bore) with an inner diameter of 260mm, an outer diameter of 400mm, and a width of 104mm. The core function is to provide high rigidity, self-aligning capability, and adaptability to fluctuating loads for the shaft systems of heavy-duty equipment such as metallurgical continuous casting machines, mining ball mills, cement mill rolls, port portal cranes, and large-scale paper machinery, which are heavy and have shaft systems prone to misalignment and with vibration and shock conditions. F3 represents a specific clearance/inner ring combination (mostly made of stamped steel inner rings to accommodate medium load fluctuations, and some brands offer optimized clearances to adapt to temperature changes and operational shocks). It can compensate for ≤2° coaxiality errors and can withstand extremely large radial loads and bidirectional axial loads. It is suitable for low to medium-speed, harsh operating conditions, and scenarios requiring high stability, cost control, and batch adaptability of heavy-duty general-purpose equipment. It is a reliable supporting component for heavy-duty general-purpose shaft systems with high load-bearing capacity, resistance to eccentric loads, low cost, and ease of maintenance. It is particularly suitable for heavy production lines and general heavy-duty equipment shaft systems that require rapid batch replacement and no extreme shocks.
