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
She’s the muscle with manners. The 220 mm bore gives her the grunt
to shove the heaviest molds, yet the 140 mm rod stays
arrow-straight so nothing wobbles. Dual-action means she pushes and
pulls with the same steady heartbeat—no lazy spring to blame.
OEM-fit dimensions slide straight into your press like they grew
there, saving you from midnight cursing. Premium seals laugh at 60
bar peaks and keep the oil where it belongs: inside, not on your
boots. From first shift to the thousandth, she whispers, “Easy,
I’ve got this,” and you suddenly believe machines can be gentle
giants.
Application scenes :Picture a sun-baked brick plant: pallets of clay slam into shape
while this cylinder cushions every hit so the foreman’s coffee
stays in the cup. Or a quiet medical-device clean room where it
nudges tiny valves into place with surgeon calm. From forging
presses roaring like dragons to plastic-injection lines humming
like bees, it slips into any scene that needs raw force delivered
with velvet gloves. If your job is to move the world without
shaking it, this is the hand you want to hold.Application | Engineering machinery, mine, shipping, metallurgy, water
