Excavator Center Swivel Joint 618-7877 545-0628 589-9800 for E395GC Excavator

This hydraulic swivel joint, identified by part numbers 618-7877, 545-0628, and 589-9800, is the central hydraulic distribution unit specially designed for the E395GC excavator hydraulic system. It transmits high-pressure hydraulic oil between the upper rotating body and the lower chassis to support travel and other hydraulic functions. Featuring a precision sealing structure, anti-wear alloy material, and precision machining, it offers direct replacement installation and stable oil supply performance for heavy-duty mining and construction working conditions.

• Internal seal ring wear, causing hydraulic oil leakage from the joint surface
• Oil channel blockage, resulting in insufficient flow and weak travel action
• Abnormal friction noise during rotation
• Seat surface scratches leading to pressure loss
• Casing deformation caused by impact and overload

• Confirm the part number and machine serial number before ordering
• Check oil port quantity, mounting dimension, and seal specification
• Request strict pressure and leakage testing before shipment
• Shockproof wooden packaging to avoid transit damage
• Quality warranty covering manufacturing defects
