Hitachi ZAX200 Excavator Center Joint Rotary Swivel Joint Oil Distributor Assembly 360 Degree Rotation

Hitachi ZAX200 Excavator Center Joint Rotary Swivel Joint Oil Distributor Assembly

This center joint (also called center pipe assembly, swivel joint or oil distributor) is built as a direct replacement for the Hitachi ZAX200 excavator. It is mounted between the upper structure and the undercarriage, transferring hydraulic oil from the rotating deck to the travel motors while allowing full 360 degree rotation. The body is machined from cast steel with a ground sealing surface, fitted with high pressure seals and a thrust bearing set, then assembled and pressure tested before packing.

Key Selling Points

• ZAX200 Excavator Center Joint Assembly — complete unit with body, center shaft, seal kit, bearing and mounting flange, ready for direct installation without modification.
• Hitachi Rotary Swivel Joint Replacement — sealing surfaces ground to original tolerance so the joint holds pressure on travel and swing circuits and stops oil leakage at the deck.
• 360 Degree Hydraulic Oil Distributor — smooth rotation with low torque, stable oil flow to the travel motors, and each unit pressure tested before shipment.
