Below is a list of Tie Rod Hydraulic Cylinders manufacturers from Rockford, Illinois. Tie rod hydraulic cylinders, like all hydraulic cylinders, convert the hydraulic energy of pressurized fluid into mechanical energy used to generate linear force and motion. Tie rod cylinders, however, are reinforced by one or more steel rods located around the outside diameter of the cylindrical barrel. This allows their use as heavy duty and high pressure hydraulic cylinders in a number of industrial settings. Because the rods have a high tensile strength, they bear much of the load placed on the cylinder thereby allowing much greater load to be applied without risk of damage to the unit.
