XCMG 860553190 Center Rotating Body Repair Kit
●XCMG 860553190 Repair Kit Technical Support
●The 860553190 Center Rotating Body Repair Kit (中央回转接头修理包 / Center Swivel Joint Seal Kit / Central Rotary Body Seal Kit / Ремкомплект центрального поворотного коллектора / Kit de sellos de junta rotativa central) is an overhaul dynamic seal kit engineered for XCMG hydraulic excavators.
●Material number 860553190 is factory-matched for the excavator central rotating body assembly (such as XCMG 800369740 Central Rotating Body / 310306403 Center Rotary Body Assembly). Positioned between the rotating inner spindle and the stationary outer housing at the machine swing axis, it provides multi-circuit high-pressure hydraulic fluid isolation. It seals independent oil channels dedicated to left and right travel motors, dozer blade cylinders, 2-speed travel solenoids, and case drain return lines. Comprising low-friction PTFE step seals, high-elasticity NBR/FKM O-rings, and heavy-duty dust wipers, it maintains 360-degree continuous unlimited rotation under full system pressures, eliminating cross-port fluid bypass, preventing track drift, and ensuring reliable track propulsion during intensive excavation, trenching, and grading operations.
●Verify center swivel joint assembly number, spool shaft diameter, circuit port count, and hydraulic working pressure range prior to order confirmation.
