23040CAK/W33

23040CAK/W33 is a double-row self-aligning roller bearing with an inner diameter of 200mm, an outer diameter of 310mm, and a width of 82mm (CA represents symmetrical spherical rollers + double flanges on the inner ring + copper alloy manufactured cage, K represents 1:12 conical hole compatible locking sleeve/retention sleeve, and W33 represents the outer ring with lubrication grooves and 3 lubrication holes). The core function is to be a shaft system support component that can withstand heavy loads and long-term cycles, featuring high load capacity, self-aligning property, convenient assembly and disassembly, and online lubrication replenishment capabilities. It can compensate for an installation misalignment of 2°, bear large radial loads and bidirectional medium axial loads. The conical hole combined with the locking sleeve can quickly position, disassemble, and flexibly adjust the radial clearance on a smooth shaft without a shoulder. The copper alloy cage enhances impact resistance and rigidity. The lubrication structure of the outer ring W33 supports online lubrication replenishment, suitable for equipment with heavy loads, large vibration and impact, frequent maintenance and disassembly, installation misalignment, and requirements for long-term stable operation, such as metallurgical rolling mill support rollers, mining crushers eccentric shafts, cement vertical mill separator shafts, heavy-duty reducers input shafts, port loading and unloading equipment rotation mechanisms, etc. Compared to the CAK model without W33, the lubrication grooves and holes of the outer ring of W33 can replenish lubricating grease during non-maintenance or rapid maintenance shutdown, extending the maintenance cycle and bearing life. Compared to the cylindrical hole CA model, it is more suitable for smooth shaft installation and high maintenance frequency scenarios. It is the preferred support solution that balances bearing reliability, self-aligning compensation, on-site assembly and disassembly efficiency, and online lubrication maintenance convenience in heavy-load, maintenance-intensive, and long-term stable operation scenarios. It can stably support and reduce overall operation and maintenance costs in environments with vibration and impact and limited maintenance conditions.
