249/1120CA/W33

249/1120CA/W33 is a self-aligning roller bearing. Its core function is to withstand heavy loads and impact loads in medium and large-sized mechanical equipment. From the perspective of the bearing type, 249/1120CA/W33 belongs to a self-aligning roller bearing. This type of bearing has two rows of spherical rollers, the outer ring has a common concave spherical raceway, and the inner ring has two concave raceways inclined at an angle to the axis of the bearing. This structure enables it to have self-aligning capability, which can compensate for the misalignment of the shaft and the bearing housing or the concentricity error caused by the deformation and bending of the shaft. From the analysis of the model meaning, "CA" indicates that the bearing uses an integral brass machined cage, with small flanges on both sides of the inner ring, no central flange, and the rollers are arranged symmetrically, featuring high rigidity and impact resistance, suitable for heavy-duty conditions; "W33" indicates that the outer ring has a ring-shaped oil groove and three oil holes, which can improve the lubrication performance of the bearing. From the perspective of application fields, self-aligning roller bearings are mainly used in various mechanical equipment in industries such as steel, mining, papermaking, shipbuilding, textile machinery, coal grinding machines, power, etc. The 249/1120CA/W33, this large-sized self-aligning roller bearing, is more focused on playing a role in large-scale equipment with higher requirements for bearing capacity and self-aligning performance, such as large rolling mills, mining crushers, large motors, etc.
