Good Hydraulic Cylinders – We Make Sure Inside PartsThe tube follows GUOYUE CD250 style.
Tube steel can be 45#, 42CrMo, or 27SiMn.
Hole is ground to H8 and feels smooth, Ra under 0.4 μm.
Head, base, ears, and piston are only 45# steel.
We do not use cast iron or cast steel. Slow-Down Parts
You can pick fixed bumpers or floating bumpers so the rod slows
down safe at any speed or load. Welds
We hit every heavy-load weld with ultrasound.
This takes away most of the stress and makes the weld last longer.
Seals
We only use top seals from NOK (Japan), Trelleborg (Sweden), Merkel
and GP (Germany).
We do not use local seals. Checks
Each cylinder is tested to GB/T15622-2005 and our own
Q/GAKY014-2023.
You get a test sheet and a pass paper. Promise
We give one year cover from ship date.
If it breaks because of how we made it, we fix or swap it for free.
This cylinder is strong. It uses thick steel and hard rod. It does
not bend. The seal keeps oil in, no leak. It has many tubes that
slide out one by one. It lifts high but stays short
Advantages: This hydraulic cylinder is like a superhero for underwater jobs.
Made from titanium alloy and stainless steel, it’s super strong and
won’t rust, even in deep - sea conditions. The high - pressure
sensor valve group means it can handle intense underwater pressure
and still work perfectly. It’s custom - made to fit your exact
needs, so it’s like having a tailor - made tool that’s built to
last. Whether you’re lifting heavy objects or operating machinery
underwater, this cylinder is your reliable underwater assistant.
Application Scenarios: Imagine working on an underwater construction project or
operating a subsea oil rig. This hydraulic cylinder is perfect for
those tough underwater jobs. It’s great for lifting heavy
equipment, operating underwater robots, or controlling valves in
deep - sea conditions. The titanium alloy and stainless steel
materials mean it can withstand the harsh saltwater environment.
Whether you’re repairing a pipeline or installing underwater
structures, this cylinder gives you the power and reliability you
need to get the job done safely and efficiently.
