23944CA/W33

23944CA/W33 is a self-aligning roller bearing. Its core function is to provide stable and reliable rotational support for mechanical equipment that bears heavy loads, has issues with misalignment of the shaft system, and requires continuous lubrication. It is based on a complete brass cage (with the CA suffix) and an inner ring without an intermediate guard. It is suitable for medium-speed heavy-duty conditions and can simultaneously withstand large radial loads and bidirectional axial loads. The design of the outer ring with oil grooves and oil holes (with the W33 suffix) facilitates lubrication replenishment, optimizes heat dissipation, and reduces friction and wear. At the same time, the spherical outer ring raceway has the ability to automatically self-align, which can compensate for the bending deformation of the shaft and installation errors, avoiding internal stress concentration. Therefore, it is widely applicable to equipment such as mining crushers, metallurgical rolling mills, cement rotary kilns, and high-temperature boiler fans, ensuring the long-term stable operation of the equipment under heavy loads, complex installation, or high-temperature conditions.
