Oem 200 100-75 Lock the Oil Cylinder for Machine Tools and
Industrial Equipment Custom Heavy-Duty 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 steadfast hand that snaps shut and never lets go. With a
200 mm grip and a compact 100-75 mm stroke, she locks tools and
dies like a big brother’s hug—tight, calm, reassuring. Chrome rod
shrugs off coolant, chips, and the occasional curse, while custom
ports mean she bolts straight in, no shims, no drama. Day after
noisy shift she whispers, “Sleep tight, I’ve got the load,” and the
machine rests easy.
Application scenes:Picture a midnight CNC shop: she clamps a mold while sparks fly
like fireflies, keeping the cut true until the coffee’s gone. Or a
forge press pausing between blows, holding ton-heavy dies steady
while steel glows like sunrise. From stamping fenders to locking
turbine blades, she’s the quiet click that keeps heavy industry
humming and hearts un-rattled.
