Oem Non Standard Metallurgical Hydraulic Cylinders for Metallurgical Engineering Built-In Seal Groove Cylinder 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 quiet hero that never sweats under a volcano of steel. Built non-standard for your exact curve or corner, she slides in like the missing puzzle piece—no shims, no midnight cursing. Inside, a built-in seal groove hugs each O-ring like a lifelong friend, keeping 1 600 °C kisses and gritty scale outside where they belong. Chrome skin laughs at sparks, balanced oil paths keep motion silky, and every push feels like a gentle promise. Day after fiery day she whispers, “Easy, I’ll hold the heat,” and the crew finally trusts the metal more than their nerves. Application scenes
Picture sunrise at the caster: white-hot slabs glide forward, and this cylinder breathes the mold open so the next perfect bloom can be born. Or a ladle tilting like a giant teapot—she times the pour so sparks paint the sky but never the floor. From blast-furnace runners to continuous casters humming lullabies, she’s the steady heartbeat keeping steel—and people—safe.
