Oem Hot Selling the Middle Ear Shaft of the Link Head Is Equipped with Sensors Servo Hydraulic Cylinders 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:
She’s the quiet genius in the middle of the link. A tiny sensor nestles inside the ear shaft like a heartbeat, telling the servo exactly where every micron lives—no guessing, no jerky surprises. Oil and electrons talk together in a smooth whisper, so the rod glides instead of jumps. OEM curves fit your joints like they were sketched over coffee, no shims, no late-night cursing. Hot-selling because she turns brute muscle into fingertip grace; long days feel shorter when the machine listens like a friend. Application scenes:
Picture a glass-panel robot on a skyscraper ledge: it leans, tilts, kisses the wall—no cracks, no sweat. Or a stage lift rising beneath a piano while the first note hangs in the air. From surgical arms cradling hearts to car-plant welders dancing around fenders, this servo cylinder is the unseen choreographer. Wherever motion needs to be gentle, exact, and worry-free, she’s already there, humming the perfect move.
