Oem Industrial Hydraulic Cylinders Hydraulic ram for Engine Hoist
Rotary Telescopic 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 gentle giant who lifts with a whisper. Custom-built for
engine hoists, this rotary telescopic hydraulic ram slides into
place like a well-loved tool—no shims, no swearing. Telescopic
design means she can reach far but fold small, saving space while
delivering power. High-grade seals and chrome skin laugh at grit
and dust, ensuring every lift is as smooth as silk. Every day she
whispers, “I’ve got this,” and the operator feels the machine run
smoothly without a hitch.
Application Scenarios: Picture a busy workshop at dawn: this cylinder powers the engine
hoist, lifting heavy engines with a gentle hiss and placing them
perfectly on the bench. Or a garage where she helps position
engines for repair, ensuring every part is perfectly aligned. From
automotive repairs to heavy machinery maintenance, she’s the quiet
heartbeat that keeps the job moving smoothly, turning brute force
into gentle precision.
