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 falters. A 160 mm heart and 110-550 mm stroke give her the strength to lift and the grace to move with precision. Double-acting muscles push and pull with equal strength, while telescopic stages unfold like a lazy yawn, reaching far without a shudder. Cushioning at the end of each stroke means she stops softly, protecting your load and your nerves. Day after day she murmurs, “Lift high, I’ve got your back,” and the operator feels the weight without the worry made-in-china.com . Application scenes:
Picture a busy workshop at sunrise: she lifts a massive engine block with a gentle hiss, placing it perfectly on the bench. Or a construction site where she helps a crane lift beams into place, stretching tall without a tremor. From loading docks to dredging barges, she’s the quiet heartbeat that keeps machinery moving
