The tube follows GUOYUE CD250 style.

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

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 little sister who lifts like a giant. 50 mm bore, 35 mm rod, 80 mm stroke—compact, yet packed with heart. Base flanges hug the frame like a favorite pair of boots, no wiggle, no whine. Synchronized ports let her dance in perfect step with her twins, so every lift feels like one smooth thought. OEM custom means she arrives already speaking your machine’s language—no shims, no midnight cursing. Under dust, rain, or blazing sun, her seals stay soft and her mood stays calm, whispering, “We’re in this together,” while the crew finishes early and heads home smiling. Application scenes :
Picture a mobile scissor lift sliding into a narrow warehouse aisle, raising pallets of books without bumping a single shelf. Or a solar farm at dawn, rows of trackers tilting in unison to catch the first golden kiss of light. From food-packaging lines that cradle delicate trays to small dam gates opening like polite doors for spawning fish, this cylinder slips in quietly, lifts gently, and keeps the rhythm right. Wherever space is tight and harmony matters more than horsepower, she’s already humming the perfect tune.
