Oem China Hydraulic Cylinder Storz China Hydraulic Cylinders Pumps explosion - proof hydraulic cylinder Good Hydraulic Cylinders – We Make Sure Inside Parts
The 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.
Advantages: 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 She’s the strong and reliable partner for tough jobs. Custom-built in China, this explosion-proof hydraulic cylinder is designed to handle high pressure with ease. High-grade materials and precision engineering ensure it withstands the rigors of demanding environments, whispering, “I’ve got this,” every time it’s called into action. Explosion-proof design means it can operate safely in hazardous environments where electrical sparks must be avoided . Application Scenarios: Picture a bustling construction site: this cylinder powers the machinery that lifts and moves heavy materials with precision and stability. Or in a coal mine where it helps control machinery, ensuring every part is perfectly aligned. From digging foundations to handling heavy loads in industrial settings, it’s the quiet hero that keeps operations running smoothly .
