 F-1140 Steel hydraulic cylinder is a system that transforms the energy of a pressurized hydraulic fluid into linear movement. To achieve this transformation, the hydraulic cylinder uses a hydraulic piston that moves up and down inside a casing, transferring the pressure from the hydraulic fluid to a piston rod , which is the element that transmits the mechanical force. The hydraulic cylinder also has sealing caps and seals that ensure it is kept airtight. At Datong Hydraulic , the standard material used to manufacture our hydraulic cylinders is F-1140 structural steel, but depending on the client’s requirements, cylinders can be made in other carbon steel like AISI 4140 4340 and 42Crmo4.  stainless steel 304 316 or even with duplex stainless steel 2205. The applications for a F-1140 steel hydraulic cylinder can essentially be divided into 5 main groups: agriculture, mobile equipment, industrial equipment, public works machinery, and machinery for environmental management.

 For the design of  hydraulic cylinders , speed and power must be calculated in dependence of the existing pressure in the cylinder space and the volume flow available. For this, the admissible values for the operating pressure in dependence of the pressure series and the admissible oil speed in the hydraulic ports must be taken into account.

A  cylinder  that has an excessive reach poses the risk of buckling – meaning that the rod and barrel have to be engineered to be larger. However, this increase in area would have a bigger force, potentially over engineering the fabrication and making it heavier.
