23076CAK/C2W33S0

23076CAK/C2W33S0 is a double-row self-aligning roller bearing with a 1:12 conical hole (CAK), smaller radial clearance (C2), an outer ring with a ring-shaped lubrication groove and oil injection hole (W33), S0-level dimensional accuracy and rotational accuracy. Its core function is to provide high rigidity and heavy-duty support for critical shaft systems of heavy-duty and medium-speed equipment such as metallurgical rolling mill rolls, mine crushing machine main shafts, cement mills, port cranes' rotating mechanisms, large-speed reduction machine low-speed shafts, etc. The self-aligning performance compensates for installation errors and shaft deflection. The conical hole is combined with a locking sleeve/retention sleeve to achieve convenient assembly and disassembly and precise control of interference fit. The brass solid cage is suitable for heavy-duty and strong-vibration as well as temperature fluctuation working conditions. The W33 lubrication structure supports online oil replenishment to extend maintenance cycles. The C2 small clearance is suitable for heavy-duty working conditions with high requirements for rotational accuracy and rigidity. The S0-level accuracy ensures low vibration and low noise operation. It is compatible with heavy-duty and medium-speed main equipment in industries such as metallurgy, mining, building materials, ports, and power, meeting the core requirements of high precision, high reliability, and long-term stable operation of heavy machinery. It is particularly suitable for heavy-duty and medium-speed working conditions with high requirements for the convenience of bearing assembly and disassembly, operational accuracy, and vibration resistance.
