90R180 Swash Plate
The 90R180 swash plate is one of the core components in the Eaton 90 Series axial piston pump. It controls the tilt angle of the pump’s rotating group, thereby determining piston stroke, flow rate, and pressure output. The precision and strength of the swash plate directly affect the pump’s efficiency, stability, and responsiveness. Halies manufactures the 90R180 swash plate using high-strength alloy steel, carburized, quenched, and precision-ground to ensure outstanding rigidity, surface hardness, and wear resistance—providing reliable performance even under high-pressure, high-temperature, and heavy-duty conditions.
