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 steel heart that keeps two dozer blades breathing as one. Custom-built, she slides into your machine like it was sketched around her. Double-acting muscles push and pull in perfect mirror steps, while hidden oil paths whisper “stay in line” so the blade never winks or wobbles. High-grade seals laugh at grit and desert heat, keeping drama outside where it belongs. At 125 mm she’s broad-shouldered, at 70-150 mm stroke she’s graceful; together they spell calm confidence. Day after dusty day she murmurs, “I’ve got your back,” and the operator grins instead of sweats. Application scenes:
Think sunrise on a new highway cut: twin dozers crawl like synchronized dancers, carving red earth without a single ridge between them. Or a wildfire line at dusk, blades skimming inches from flaming brush, saving homes while sparks kiss the night sky. From swampy land-reclamation projects to icy mining haul roads, this cylinder turns brute iron into ballet. Wherever two blades must move as one heartbeat—bulldozers, graders, heavy reclaimers—it’s the quiet promise that tomorrow’s ground will be level and tonight’s crew will sleep easy.
