Hydro pneumatic booster cylinder: working principle
The hydro pneumatic cylinder working principle is simple: a large air piston pushes a small hydraulic plunger, and because the areas differ, the oil pressure and output force rise many times over the air pressure. That makes a hydro pneumatic booster cylinder ideal when a fast approach stroke is followed by a short, high-force working stroke. A hydro pneumatic cylinder for ATC spindle tool release pushes the drawbar against its disc springs; a hydro pneumatic cylinder for lathe chucking or fixture clamping holds parts firmly.
Pneumatic cylinder for CNC vs hydro-pneumatic
A plain pneumatic cylinder for CNC use is fast but limited in force by air pressure and bore. Where you need more force in the same space, a hydro-pneumatic unit is the answer. Hydro pneumatic cylinder price depends on force, stroke and mounting.
If you are comparing a hydro pneumatic cylinder manufacturer or supplier in India, ask for the rated force at your air pressure, stroke, oil type and seal life. For hydro pneumatic cylinder repair, such as an oil leak or loss of force, send the model and symptoms and we will advise on seals or a replacement.
Hydro-Pneumatic Cylinder: frequently asked questions
How does a hydro-pneumatic cylinder work?
Compressed air drives a large piston that pushes a small plunger into an oil chamber. Because force equals pressure times area, the small plunger raises oil pressure many times above the air pressure, and that oil drives the output piston. The cylinder moves fast on air, then applies high force for the short working stroke.
Where are hydro-pneumatic cylinders used in CNC?
They are used to release tools in ATC spindles of machining centres, to clamp parts in fixtures, to actuate lathe chucks and for pressing, riveting and punching stations. Anywhere a machine needs high force over a short stroke but has only shop air, a hydro-pneumatic cylinder avoids a separate hydraulic pack.
