23028CA/W33

The core positioning of the 23028CA/W33 bearing is a double-row self-aligning roller bearing with high load-bearing capacity and excellent lubrication performance. From a structural perspective, it belongs to a self-aligning roller bearing. The inner diameter is 140mm, the outer diameter is 210mm, and the width is 53mm. It uses a brass cage (denoted as CA), which can effectively guide the movement of the rollers and ensure the stability and service life of the bearing. The outer ring has an oil groove and three oil holes (denoted as W33), which facilitates the lubrication of the bearing and can effectively reduce friction and wear, thereby enhancing the reliability and operating life of the bearing. In terms of performance, this bearing can withstand large radial loads and certain bidirectional axial loads. It has self-aligning function, which can compensate for the concentricity deviation between the shaft and the seat hole, and adapt to the installation errors and flexural deformations of the shaft. Its rated dynamic load and static load are relatively high, and it is suitable for industrial scenarios with medium rotational speeds. In terms of application, the 23028CA/W33 bearing is mainly used in large-scale heavy machinery such as those in the mining, metallurgy, cement, and paper industries, as well as in equipment like fans and reducers that require high reliability and low maintenance.
