23028F3/W33

The core positioning of the 23028F3/W33 bearing is a high-capacity, easy-to-lubricate double-row self-aligning roller bearing with an inner diameter of 140mm, an outer diameter of 210mm, and a width of 53mm. The "F3" marking indicates that the internal structure has been optimized to adapt to complex working conditions such as impact, vibration, or specific temperatures. The "W33" represents that the outer ring has lubrication grooves and three oil holes to support the long-term replenishment of lubrication, and it also has the self-aligning performance that automatically compensates for the installation error and deflection deformation of the shaft, capable of withstanding large radial loads and certain bidirectional axial loads. It is suitable for heavy-duty and highly-vibratory large-scale heavy equipment such as mining machinery, metallurgical equipment, heavy reducers, and large fans.
