Presión nominal: The rated operating pressure of the 703-11-53203 swivel joint assembly is typically around 350 – 400 bar (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.
Máxima presión: The maximum pressure that the joint can withstand for short periods is usually higher than the rated pressure, alcanzando 450 bar (45 MPA) o más. 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.
