23056CA

23056CA is a double-row symmetrical self-aligning roller bearing with an inner diameter of 280mm, an outer diameter of 420mm, and a width of 106mm (CA represents the symmetrical roller design, which distributes the load more evenly). The core positioning is for the working rolls/support rolls of metallurgical rolling mills, the hollow shafts of mining ball mills, the grinding rollers of cement vertical mills, the rotating mechanisms of port cranes, the input and output shafts of large heavy-duty reducers, etc., which are subjected to extremely large radial loads and bidirectional medium axial loads, and where the shafting is prone to bending due to heavy loads or installation errors, and where the stability of the bearing operation and the uniformity of the load-bearing are highly demanded for the shafting of heavy equipment. It provides high rigidity, strong load-bearing capacity, and self-aligning reliability support for these shafting systems that are subject to heavy loads and are prone to misalignment due to heavy loads or installation errors, and where the bearing operation stability and load-bearing uniformity are highly demanded. Its symmetrical roller design allows the load to be evenly distributed between the two rows of rollers, is suitable for long-term continuous operation under low to medium speed, heavy-load, and strong impact conditions, can compensate for ≤2° coaxiality deviation of the shafting, and can tolerate load fluctuations in the working conditions. It is a key basic component for ensuring the operational accuracy, reducing failure risks, and extending maintenance cycles of heavy-load equipment shafting systems, especially suitable for heavy-load scenarios with more stringent requirements for bearing load-bearing uniformity and operational stability.
