23064CAK

23064CAK is a double-row tapered-hole self-aligning roller bearing with an inner diameter of 320mm, an outer diameter of 480mm, and a width of 121mm. Its core function is to provide a high-strength, long-lasting, and reliable support for the core shaft systems of heavy-duty, low-to-medium speed equipment such as metallurgical rolling mills, mining crushers, cement mills, and port cranes, which can be quickly installed and positioned through locking sleeves and adapt to thermal expansion and misalignment conditions of the shaft system. The CA type brass integral cage ensures stable operation and heat dissipation efficiency under heavy loads. The K indicates that the 1:12 tapered hole is compatible with locking sleeves to achieve quick concentric installation and axial pre-tightening, capable of withstanding large radial loads and bidirectional light axial loads, and having a self-aligning capability of ≤2° to cope with shaft deflection and installation misalignment. The basic rated dynamic load is approximately 2348kN, the static load is approximately 3800kN, the grease lubrication limit speed is approximately 630r/min, and the oil lubrication is approximately 800r/min. It is suitable for heavy equipment shaft systems that require heavy-duty vibration, large temperature fluctuations, convenient installation and positioning, and quick maintenance and replacement, helping to improve equipment operation reliability and maintenance efficiency.
