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: This heavy - duty hydraulic cylinder is like a strong, dependable workhorse for your metallurgical equipment. It’s built to handle massive loads and tough conditions without breaking down. The durable materials mean it can withstand the high temperatures and heavy wear typical in metallurgical processes. Plus, it’s designed for long - lasting performance, so you can rely on it day in and day out. Whether you’re lifting heavy beams or operating presses, this cylinder is your trusty partner, making your job easier and more efficient. Application Scenarios: Think of a bustling steel mill or a busy foundry. This hydraulic cylinder is perfect for those demanding environments. It’s ideal for operating heavy - duty presses, lifting massive steel beams, or handling molten metal. Whether you’re forging steel, operating a rolling mill, or maintaining heavy equipment, this cylinder provides the brute force and precision you need. It’s also great for lifting large molds or operating gates in a metal - processing plant. If your job involves heavy - duty lifting or moving in extreme conditions, this cylinder is your go - to solution.
