23076CAK/W33

23076CAK/W33 is a double-row self-aligning roller bearing with a 1:12 conical hole (CAK) and an outer ring with a ring-shaped lubrication groove and an oil injection hole (W33). The core function is to provide high rigidity and heavy-duty support for key shaft systems of heavy-duty and medium-low speed equipment such as metallurgical rolling mill rolls, main shafts of mining crushers, cement mills, rotating mechanisms of port cranes, and low-speed shafts of heavy reducers. Its self-aligning performance can compensate for installation errors and shaft deflection. The conical hole is combined with a locking sleeve / disassembly sleeve to achieve convenient assembly and disassembly and precise control of interference fit. The brass solid cage is suitable for heavy-load, strong-vibration and temperature fluctuation working conditions. The W33 lubrication structure supports online grease replenishment to extend maintenance cycles. It is suitable for heavy-duty and medium-low speed main equipment in industries such as metallurgy, mining, building materials, ports, and power, meeting the core requirements of high reliability and long-term stable operation of heavy machinery. It is particularly suitable for heavy-duty and medium-low speed working conditions with high requirements for the convenience of bearing assembly and disassembly and anti-vibration performance.
