23076CA/C3W33

23076CA/C3W33 is a double-row self-aligning roller bearing (the CA type features double-sided flanges on the inner ring and a brass solid cage, while C3 is designed to increase the radial clearance, and W33 has a ring-shaped lubrication groove and an oil injection hole on the outer ring). The core function is to provide high-strength, long-life support for critical shaft systems of heavy-duty, low-to-medium speed equipment such as metallurgical rolling mills, mining crushers, cement mills, port cranes, and large reducers. This support is capable of withstanding heavy loads, resisting skewing, and being lubricated online, and is suitable for thermal expansion and vibration conditions. Its self-aligning property can compensate for installation errors and shaft deflection. The C3 clearance is adapted to heavy-load, strong vibration, and situations with significant temperature variations. The W33 lubrication structure enables continuous replenishment of lubricating grease to extend the maintenance cycle. The cylindrical bore design facilitates assembly and disassembly while allowing precise control of the radial clearance. It is suitable for heavy-duty, low-to-medium speed main equipment in industries such as metallurgy, mining, construction materials, ports, and power, meeting the dual requirements of efficient maintenance and long-term stable operation of heavy machinery. It is particularly suitable for heavy-duty conditions with high requirements for bearing vibration resistance, self-aligning ability, and online lubrication.
