Oem 140 100-600 Turbocharged Hydraulic Cylinder General Hydraulic Cylinder for Excavator Rotary Hydraulic Cylinder 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
Plain-English Advantages:This OEM 140/100-600 turbocharged rotary cylinder is built for excavators that need strong, smooth swings. The “turbo” porting packs extra punch without extra fuel, while the forged barrel and chrome rod laugh off dirt, heat, and 250 bar spikes. Pick your mounts, paint, and sensor spots—samples leave the factory in days, and the price skips the middleman. No leaks, no squeaks, just reliable spin.
Plain-English Uses:Perfect for swinging an excavator’s boom, rotating a grapple on a scrap yard crane, or turning the arm on a drilling rig. Any job that needs a compact cylinder to spin heavy loads fast and steady—on job-sites from city digs to riverbanks—this one steps up and keeps you digging.
