Oem Electric Hydraulic Cylinder 140-180 Double Rack Swing Hydraulic Cylinder Rubber Plate Vulcanizing CylinderGood 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 smooth dancer inside the press. With 140–180° of double-rack swing, she pirouettes molds and platens like a seasoned waltz—no jerk, no clang. Electric brains read every degree, so rubber flows and cures just right, every time. Hard-chrome rod shrugs off heat and sticky compound, while built-in cushions kiss each stop like a lullaby. OEM curves mean she bolts straight in—no shims, no midnight swearing. Day after hot-plate day she whispers, “Spin easy, I’ll keep the cure perfect,” and the vulcanizer hums instead of hiccups.
Application scenes:Picture dawn at a tire plant: molds swing open like giant clamshells, releasing fresh tread while she folds quietly for the next load. Or a conveyor-belt shop where she tilts heated platens so endless rubber belts fuse without a wrinkle. From shoe soles to giant dock fenders, she’s the graceful turn that turns raw rubber into tomorrow’s grip on the road.
