Customized Professional Hydraulic Cylinder for Coil Turnover Machine 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 strong, careful friend who flips tons like pancakes. Built just for your coil-turnover rig, she slides in like the missing puzzle piece—no shims, no swearing. A built-in seal groove hugs each O-ring like a lifelong promise, keeping oil in and dust out. Chrome skin shrugs off metal burrs while balanced flow keeps every turn smooth, quiet, and coffee-spill-proof. Day after day she murmurs, “Easy, I’ll cradle the coil,” and the operator quits bracing for bangs.
Application scenes:Picture a steel service center at sunrise: a 20-ton roll glides skyward, flips gently, then lands soft as a feather for the next cut. Or a cable plant at dusk where copper coils pirouette without nicking a single strand. From aluminum mills to tire factories, she’s the gentle hand that turns brute weight into ballet, letting shifts end early and backs stay happy.
