  Single rod cylinders are cylinders with a one-side chrome piston rod and thus with a large piston area for extension and an area for retracting that is reduced by the piston rod area..The cylinder's main parts are the piston, the piston rod, the cylinder tube , gaskets and seals. Single acting cylinders also have a spring inside the cylinder. A single acting cylinder works with compressed air to actuate the piston in one direction and spring force to return to the base position. A single acting hydraulic cylinder is simpler, so there is less to maintain. With only one line the action of the cylinder is determined entirely by the pressure on that one line. They often have a spring or something similar to push or retract the piston rod, but they might rely on the force on end to push it back. Simplicity is always good for equipment that needs to be rugged and reliable.

  STKM13C   hydraulic steel tube   is a high-precision steel material that is produced through cold drawn or hot rolled hear treatment. It is primarily used for the hydraulic cylinder or pneumatic cylinder filed.

 42CrMo4/DIN 1.7225 steel is a commonly used grade contains Chromium-Molybdenum elements in European standard EN10083 and EN10250. 42CRMO4 Steel Bar has good strength and toughness,and good low-temperature impact toughness which are mostly used after quenched and tempered heat treatment. DIN 1.7225 / 42CrMo4  is widely used in large size and important parts,such as axle,gear,connecting rod,engine hydraulic cylinder ,spring,oil drill pipe joints and pinions. 1.Chemical Composition Grade C Si Mn P S Cr Mo 42CrMo4/1.7225 0.38-0.45 ≤ 0.4 0.6-0.9 ≤ 0.025 ≤ 0.035 0.9-1.2 0.15-0.3 4140 0.38-0.43 0.15-0.35 0.75-1.0 ≤0.035 ≤0.035 0.8-1.1 0.15-0.25 Related Specifications Of42Crmo4 Steel Bar ASTM :4140 JIS :SCM440 BS :EN19/708M40 GB :42CrMo Heat treatment of 42CrMo4 Steel Bar The process of 42CrMo4 steel bar alters the physical and chemical properties to meet specific requirements.
