1830mm Welded Hydraulic Cylinder Design

I need a production-ready design for a double-acting welded hydraulic cylinder that will be installed on industrial machinery. Key metrics are a 1 830 mm stroke, 75 mm Ø tube (63 mm bore), and a 45 mm chrome-plated rod. The assembly must cope with elevated operating temperatures, corrosive splashes, and heavy-duty cycles, so every decision on steel grade, seal selection, and surface finishing has to reflect those conditions.

Once we start, I will share the exact mounting style and the pressure range (assume 250–300 bar for your preliminary work). What I expect from you is a complete engineering package:

• Fully dimensioned 2D drawings and 3D CAD model (STEP or native SolidWorks)
• Strength, fatigue, and buckling calculations with clear safety factors
• Seal, gland, and bearing specs suited to high-temperature and corrosive service
• Welding symbols, prep, and procedures that meet ISO/ASME cylinder standards
• Bill of materials listing material grades, coatings, and any heat-treatments
• Concise design report summarising assumptions, formulae, and validation steps
• (Optional but welcomed) FEA plots from ANSYS or SolidWorks Simulation

Let me know which software you prefer and your typical turnaround so we can lock in milestones and get this cylinder into fabrication without delay.
