23040F3

23040F3 is a double-row self-aligning roller bearing with an inner diameter of 200mm, an outer diameter of 310mm, and a width of 82mm (F3 usually refers to cylindrical bore + special radial clearance group / adapted to specific working conditions through structural optimization, symmetrical spherical rollers + double flanges on the inner ring, commonly made of stamping or copper alloy cages). The core function is to serve as a basic type shaft support component for heavy-duty applications, featuring high load-bearing capacity, self-aligning property, and universal adaptability. It can compensate for an installation misalignment of 2°, withstand large radial loads and bidirectional medium axial loads. The cylindrical bore is suitable for regular installation with a bossed shaft neck, without the need for locking rings / release rings. The structure is simple and the cost is controllable. It is suitable for heavy-duty equipment with high installation positioning accuracy requirements, stable loads, and long maintenance cycles. Compared to the conical bore K-type, it is more suitable for fixed bossing and less maintenance scenarios. Compared to the model with W33 lubrication slot holes, it is more suitable for scenarios with good sealing and regular lubrication maintenance. It is the preferred basic support solution for heavy-duty, low-vibration and shock, stable installation reference, and high cost-effectiveness and long lifespan equipment such as work rolls of metallurgical rolling mills, press rolls of papermaking machinery, trunnions of cement rotary kilns, main shafts of heavy fans, output shafts of large reducers, etc. It can achieve a balance between high rigidity support and low operation and maintenance costs under stable working conditions.
