238/8850CA/W33

The core function of the 238/8850CA/W33 bearing is to withstand heavy loads and to meet certain self-aligning requirements in mechanical transmission systems. From the structural characteristics, this bearing belongs to a self-aligning roller bearing. The inner ring has two arc-shaped raceways, while the outer ring raceway is spherical. The center of the bearing coincides with the curvature center of the outer ring, featuring a self-aligning function. The allowable self-aligning angle is generally 1° to 2.5°, which can compensate for the installation errors between the shaft and the housing bore or the deflection of the shaft, resulting in the inclination of the inner and outer rings. The "CA" in the model indicates that the inner ring has a flange and an active retaining ring, and uses a solid brass cage. This structure enables the bearing to maintain a uniform distribution of the rolling elements during operation, improving the stability and service life of the bearing. The suffix "W33" indicates that the outer ring has oil grooves and three lubrication holes, facilitating lubrication maintenance, which can reduce friction and wear, further enhancing the performance and service life of the bearing. From the perspective of application scenarios, the 238/8850CA/W33 bearing is mainly used in metallurgical machinery, mining machinery, large fans and other large-scale mechanical equipment. These devices usually need to withstand large radial loads, and may also be subjected to certain axial loads. The large size (inner diameter of 8850mm) and high load-bearing capacity of this bearing enable it to meet the requirements of these heavy-load equipment.
