Hole is ground to H8 and feels smooth, Ra under 0.4 μm.
Head, base, ears, and piston are only 45# steel.

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.

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 friendly giant who learns your quirks instead of forcing you to learn hers. Born in a Chinese workshop that still smells of fresh coffee and welding sparks, every tube, rod, and port is cut to your daydream—no standard boxes, no “close enough.” Synchronized veins let two, three, or ten cylinders waltz as one, so the load never winks or wobbles. Factory price keeps the bean-counters smiling, while OEM-fit means she slips straight into your rig like she’s always belonged. Day after noisy day she murmurs, “Relax, I’ll move in step,” and the crew stops counting headaches. Application scenes:
Picture a sunrise bridge lift: four arms rise together, traffic pausing mid-yawn while the deck glides level as a table. Or a solar farm tilting panels in perfect unison, catching the first gold of dawn without a single panel lagging behind. From warehouse lifts stacking dreams sky-high to dredge booms carving new rivers, she’s the quiet promise that tomorrow will be straight, smooth, and on time.
