2. Design 


Not only we could manufacture all kinds of hydraulic cylinders according to the drawing from our

customers,but also we could make a design according to customer's requirements.If you 

require our engineer to make a design,pls advise us the following specification:


1. Rated pressure 

2. Working pressure 

3. Test pressure 

4. Working condition and environment ,for example ,temperature ,working frequency 

5. Pulling force ,and return stroke force

6. Pulling and return speed 

7. Assembly size  

8. Seal ring requirements .For example , brand ,seal material etc .

9. Tube and piston rod raw material requirements 

10. Piston rod surface treatment requirements, for example chromating film thickness ,   

 Surface hardness etc . 

11. Painting and other spare parts requirements .



3. Manufacturing capability and cylinder size range 


3.1 Cylinder bore diameter :max Ø1200mm 

3.2  Cylinder length :10Meter 

3.3  Max lifting capability :50 Tons 



4.Manufacturing and inspection 


4.1.Cylinder tube size and choice  


4.1.1   According to the cylinder pressure and inside diameter size ,different steel tube Would be choosed .


1.  ID ≤300mm , cold rolled precision seamless tube would be choosed 

2.  300mm≤ID ≤500mm , hot rolled seamless tube would be choosed 

3.  500mm≤ID ≤1000mm, forged tube would be choosed 


4.1.2 Cylinder tube steel grade : SAE1020 , SAE1045 ,27SiMn , S355JR ,S355J2G3

St52-3 ,SUS304 ,SUS316L etc .  

4.1.3 Cylinder tube inside boring and honing , roughness R0.2-R0.3,


4.1.4 Cylinder tube inside chromating : if necessary ,tube inside chromating could be applied 


4.2  Piston rod  is a very important part for hydraulic cylinder .


4.2.1 Piston rod steel grade : SAE1045, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L 


4.3 Seal ring and O ring 


According to the customers’ requirements and working condition , we would choose suitable 

seal ring kit , . we would supply suitable seal solution for their customer so that hydraulic cylinder has more

 lifetime , easy maintenance and simple repairing .


4.4 Tube and flange welding 


 The welding on cylinder tube and flange would be Ultrasonic tested every time , the welding seam would be 

cleaned before machining .weensure that every welding seam has no any leak during lifetime 


4.5 Assembly and pressure test


Before hydraulic cylinder is assemblied , every spare parts would be measured and cleaned .After hydraulic

 cylinder is assemblied , pressure test would be carried out one By one , eternal company ensure that testing

 pressure is higher 30%-50% than working pressure  , and pressure holding time 30~60 minutes is necessary . Every piece hydraulic cylinder must be tested completely without any leak .


 4.6 Painting and storage .


After hydraulic cylinder pass through pressure test , painting is necessary .
