Water-Cooled Circulating for Heavy-Duty Applications Synchronized
Control Cylinder 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 cool-headed big sister you want on the hottest days. A
built-in water-cooling jacket keeps the oil chilled like mountain
spring water, so seals stay soft and smiles stay wide. Synchronized
ports let two or more cylinders waltz in perfect step—no jerky
dance, no bruised cargo. OEM dimensions mean she drops straight
into your frame, no late-night cursing, no extra shims. From 80 mm
bore to 90 mm stroke, every millimeter is forged for brute
kindness, ready to shoulder the worst loads while whispering,
“Easy, I’ve got you” made-in-china.com .
Application scenes:Picture a steel mill at noon: glowing slabs glide along, and these
cylinders lift in unison without breaking a sweat—or a sweat bead
on the operator’s brow. Or a floodgate silently yawning open at
dusk, twin rams moving like oarsmen rowing the same tide. From
mining shovels biting red earth to hydro gates taming mountain
snowmelt, they turn rough work into a calm heartbeat. Wherever
heavy meets heat and harmony matters, they’re already there,
keeping the world level and the crew smiling.
