XCMG Steering Cylinder – PN 803044846 / XGYG04-019A | OEM Hydraulic Actuator

The XCMG PN 803044846​ (model XGYG04-019A) is a steering cylinder​ in the XCMG hydraulic steering system — a double-acting hydraulic actuator that converts hydraulic energy into linear motion to drive the steering linkage and steer the wheels. As a core actuator in any hydraulic system, its installation quality directly affects system performance and service life; before mounting, verify model specs (stroke, bore, rod diameter, mounting style) against the design drawing, inspect the piston rod for bending / thread damage, and torque the bolts symmetrically in steps.
