Rated Pressure: The rated operating pressure of the 703-11-53203 swivel joint assembly is typically around 350 – 400 バー (35 – 40 MPa). This pressure rating is in line with the hydraulic system pressure requirements of the PC1250-7 and PC1250-8 excavators, enabling it to effectively transfer hydraulic fluid between the stationary and rotating parts of the excavator.
Maximum Pressure: The maximum pressure that the joint can withstand for short periods is usually higher than the rated pressure, reaching up to 450 バー (45 MPa) or more. This additional pressure capacity allows the swivel joint to handle sudden pressure surges that may occur during the excavator's operation, such as when performing heavy-duty digging or lifting tasks.
