Rated Pressure: The rated operating pressure of the swivel joint assembly is typically in the range of 350 - 400 bar (35 - 40 MPa). This is consistent with the high-pressure hydraulic systems of the PC1250 - 7 and PC1250 - 8 excavators, ensuring that the joint can handle the hydraulic forces without failure.
Maximum Pressure: The joint can withstand a maximum pressure of up to 450 bar (45 MPa) for short periods. This extra pressure tolerance allows it to handle sudden spikes in pressure that may occur during the operation of the excavator's hydraulic components.
Flow Capacity: The swivel joint is designed to handle a significant flow rate of hydraulic fluid to meet the demands of the excavator's various functions. The exact flow capacity depends on the specific design and internal passage dimensions of the joint, but it is typically capable of handling flow rates in the range of 300 - 600 liters per minute (L/min) to ensure smooth operation of the hydraulic system.
