Tie-rod hydraulic cylinders are have four rods (bolts) that connect the ends of a double-acting hydraulic cylinder to add strength and stability to the cylinder and prevent it from coming apart under pressure. Double-acting tie-rod hydraulic cylinders provide power in both directions (extending and retracting), which allows for more precise movement. They have a linear actuator and are used in agricultural equipment, industrial machinery, and construction equipment to support, lift, and press heavy loads. Seals can be replaced as needed to keep cylinders in good working order. Clevis mounts on both ends allow the cylinder to be mounted directly to the equipment. The rod end has a clevis attachment that is welded to the body for strength and stability. The piston-side end cap has a clevis bracket for attaching to equipment.
