Design and Construction:
Robust Construction: Built to withstand high stress and shock loads experienced during digging and swinging with a loaded bucket.
Large Bore and Rod Diameter: The 428D features a cylinder with a large internal diameter (bore) and a thick piston rod, providing the necessary force and resistance to bending.
Piston and Seal Kit: The internal piston contains durable seals that separate the high-pressure oil on the "cap" side from the oil on the "rod" side. Common seal materials include polyurethane for excellent wear and extrusion resistance.
Mounting: Typically uses trunnion mounts or clevis mounts, which allow the cylinder to pivot slightly as the backhoe swings, preventing binding and stress.
This 279-5556 swing cylinder is used for 424D 428D backhoe loader.
