Exceptional Durability & Robust Construction
Large Bore Diameter: The 390D's cylinder is built with a large internal diameter, providing a massive piston surface area. This allows it to generate the tremendous force required for a large 90-ton class excavator to lift heavy loads and break through tough materials.
Heavy-Duty Materials: Manufactured from high-strength, alloy steel, the cylinder barrel, piston rod, and head are built to withstand extreme shock loads, constant stress, and abrasion from the harsh operating environments of mining and heavy construction.
This 470-7141 boom cylinder is used for 390D 390F excavator.
