Excavator Center Joint category provides hydraulic swivel joint (center joint) assemblies for all major excavator brands. These critical components transfer hydraulic fluid between the rotating upper structure and the fixed undercarriage, enabling continuous 360-degree excavator rotation while maintaining pressure to travel motors and track systems.
Our catalog covers center joints for mini-excavators up to large mining-class machines, from brands like CAT, Hitachi, Komatsu, Sany, Doosan, Kobelco, Volvo, and more. Each center joint features precision-machined surfaces and quality seals for leak-free operation. Also see our Excavator Final Drive and Excavator Swing Gearbox categories.
