Customizable Installation of Front and Rear Bushings with Dust
Cover 340 125-686 Mobile Hydraulic Cylinder for the Mast Good
Hydraulic Cylinders – We Make Sure Inside PartsThe 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:Like a good friend who never complains, this cylinder lets you
decide exactly how the front and rear bushings sit, so every bolt
lines up the first time, no cursing needed. The little dust cover
is the polite umbrella that keeps grit out of the works, wiping
away the worry of early wear. Together they give the mast a
smoother, quieter life—less shake, less rust, more trust. Operators
feel the difference in their bones: the lift is gentler on the load
and on the nerves, every sunrise shift starts with a confident
“we’ve got this.”
Application scenes:Picture dawn on a cherry-picker truck parked beside a row of
streetlights: the crew needs the boom to rise steady and stop on a
dime while traffic rushes by. Or imagine a farmer rolling across
muddy fields, adjusting the loader on the go so bales don’t tumble.
This cylinder slips into those moments—construction cranes, pruning
platforms, tele-handlers, even a traveling carnival ride—wherever
the mast must lift people or freight above the everyday world. It
adapts quietly, hugs the pins tight, and keeps the day running on
hope, coffee, and clean hydraulics.
