Oem Electric Hydraulic Cylinder 80 56-380 Telescopic Cushioning Hydraulic Cylinder Ceramic Press Cylinder Categories 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.
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 gentle giant who never rushes. Custom-built with an 80 mm bore and 56-380 mm stroke, this telescopic hydraulic cylinder unfolds like a slow, steady breath. Electric brains mean she moves with precision, while cushioning at the end of each stroke ensures a soft landing—no jolts, no surprises. Ceramic press technology gives her the strength to handle heavy loads while staying as smooth as silk. Every day she whispers, “I’ll carry you gently,” and the operator feels the press run smoothly without a hitch. Application Scenarios Picture a ceramics factory at dawn: this cylinder powers the press, turning powders into intricate ceramic parts with perfect precision. Or a manufacturing plant where she helps position heavy steel plates, ensuring every part is perfectly formed. From ceramic presses to heavy machinery, she’s the quiet heartbeat that keeps production running smoothly, turning brute force into gentle precision.
