g Machine Cylinder Types Good Hydraulic Cylinders – We Make Sure They Work 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.
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 when closed. It works two ways: oil pushes up, oil pushes down. Paint stops rust. Ports fit most hoses. It starts fast and stops soft. It runs hot or cold. It works all day. Fixing is simple. Price is low for the years it gives. It is light, fits small space. It holds load when power is off. It is quiet and safe. You can pick size, stroke, and ports. It meets world rules. It ships fast. You can fit it quick with no extra tools. It lifts and presses smooth. It saves power and time. It is ready for hard jobs. 应用场景(100词)
