Advantages of double acting hydraulic cylinder

Bidirectional power

Double-acting cylinders can apply force in both directions. They are ideal for tasks that require pushing and pulling.

Precise positioning

Double-acting cylinders can control movement precisely in both phases, making them suitable for applications that need precise positioning.

Shorter work time

Double-acting cylinders work on both strokes: extension and retraction. They improve efficiency and enable faster smoother cycles.

Wide range of applications

Double-acting cylinders can lift, press, and pull. They have many uses. They are common in industrial automation and heavy machinery.

Customizable stroke length

You can easily adjust the stroke length to suit different needs. It provides design and operating flexibility.

High safety

Double-acting cylinders can control movement in both directions. They won't cause sudden drops.

double acting hydraulic cylinder material

The main material we use to produce hydraulic cylinders is 45# steel. In addition to 45# steel, other materials can also be customized according to your needs. The material details are in the table below.

Material：steel Tensile Strength：MPA Yield Strength：MPA Elongation
20#   630 570 12
45#   730 680 7
16mn 640 570 13

cold drawing process 

Cold drawing is a process where metal is stretched through a die at room temperature. This technique can effectively improve the mechanical properties of steel tubes, making it very suitable for the manufacture of hydraulic cylinders.
Our cold drawing process is efficient and energy-saving, and can produce steel tubes that meet strict quality standards. These tubes are suitable for a variety of low-carbon and medium-carbon steels and alloy steels, making them able to meet the specific requirements of hydraulic cylinders in different application scenarios.
We look forward to working with you to provide you with high-quality hydraulic solutions!

Cylinder bore machining  - rolling and calendering

  • The workpiece surface is extruded and deformed by a high-hardness roller
  • The surface metal is made to flow by the principle of plastic deformation
  • A smooth and dense machining layer is formed on the workpiece surface
  • Surface quality
  • Higher surface finish can be obtained
  • Surface hardness is increased by 15-30%
  • A dense metal surface layer is formed

Piston rod material

45# steel is the material used for standard hydraulic cylinder piston rod. The production process of piston rod is heat treatment, tempering and quenching. The chrome plating process of piston rod surface is 1-5um, and the common one is 1um.

  • High quality carbon steel grades: 35, 45, 50
  • Alloy steel grade: 27SiMn, 30CrMo, 30CrMnSiA, 35CrMo, 38CrMoA1, 40Cr, 42CrMo
  • Low alloy high strength steel grades:Q335B(C,D), Q335E
  • Stainless steel grades: 20Cr13, 06Cr9Ni10, 304, 06Cr17Ni12-Mo2, 316, 12Cr18Ni9, 14Cr17Ni2

Heat treatment of piston rod

  • Tempering treatment:
    First, quench to improve material strength.
    Then temper to eliminate internal stress and improve toughness.
    Control the hardness between HRC28-32.
  • Surface hardening treatment:
    Use induction quenching or high-frequency quenching.
    The surface hardness can reach HRC52-58.
    The depth of the hardened layer is generally 1.5-2.5mm.
