Single-Acting Hydraulic Cylinder
3 month ago
Product details
**1. Product Overview**
**Single Acting Hydraulic Cylinder * * is a hydraulic actuator that is driven by hydraulic oil * * in a unidirectional manner to extend the piston rod * *, and automatically resets * * by external force (gravity/spring/load). Simple structure, low cost, widely used in light load and unidirectional force application scenarios.
**2. Core Features**
✅ ** Unidirectional hydraulic drive * * - with only one oil port (inlet), hydraulic oil pushes the piston to extend, and resetting does not require hydraulic pressure.
✅ ** Economical and practical * * - simple structure, low failure rate, and maintenance cost only 60% of double acting oil cylinders.
✅ ** Lightweight design * * - small size, light weight, suitable for small equipment (such as agricultural machinery, logistics equipment).
✅ ** Safe and reliable * * - Reset relies on mechanical force, automatically returns to its original position in case of power failure/oil leakage, avoiding the risk of loss of control.
**3. Typical structure**
|* * Component * * | * * Function * * | * * Remarks * *|
|-------------------|------------------------------------------|------------------------------|
|Cylinder barrel * * | Contains piston and hydraulic oil | Material: carbon steel/stainless steel|
|* * Piston rod * * | Unidirectional transmission of thrust | Chrome plated rust proof surface (thickness ≥ 15 μ m)|
|* * Reset mechanism * * | Spring/gravity/load achieve retraction | Spring reset type needs to be labeled with elastic coefficient|
|* * Single oil port * * | Connect hydraulic pipeline (oil inlet only) | Thread/flange interface|
**4. Analysis of Working Principle**
1. * * Extension stage * *: Hydraulic oil is injected from the oil port, pushing the piston rod outward (outputting thrust).
2. * * Reset phase * *:
-Spring reset type: After hydraulic pressure relief, the built-in spring compression force causes the piston rod to retract.
-Gravity/load reset type: relying on external mechanical force (such as the weight of the cargo hopper) to return to its original position.
**5. Main application scenarios**
-* * Agricultural Machinery * *: Tractor cargo hopper lifting and plowing control.
-Logistics equipment: hydraulic pallet truck lifting, storage rack adjustment.
-Industrial equipment: stamping machine demolding, unidirectional clamping of fixtures.
-* * Special vehicle * *: Garbage truck body self dumping (reset by gravity).
**6. Key parameter selection guide**
|* * Parameter * * | * * Description * * | * * Typical Range * *|
|-------------------|----------------------------------------|--------------------------|
|Cylinder diameter/rod diameter determines the output thrust (F=pressure x effective area) | Cylinder diameter: 32-200mm|
|* * Travel * * | Maximum extension length of piston rod | 50-1000mm (customizable)|
|* * Work pressure * * | System rated pressure | 10-16MPa (agricultural standard)|
|* * Reset method * * | Spring/gravity/external load | Spring reset requires marking the elastic force (N)|
|* * Installation method * * | Earring type, flange type, footrest type | Choose according to mechanical structure|
**7. Compare double acting hydraulic cylinders**
|* * Features * * | * * Single acting cylinder * * | * * Double acting cylinder * *|
|-------------------|--------------------------------------|----------------------------|
|* * Drive mode * * | Unidirectional hydraulic+mechanical reset | Bidirectional hydraulic drive|
|* * Control accuracy * * | Low (uncontrollable reset) | High (bidirectionally adjustable)|
|* * Cost * * | Low (saving valve groups and pipelines) | High|
|* * Applicable scenarios * * | Light load, unidirectional operation | Heavy load, requiring precise bidirectional control|
**8. Optional features**
-* * Buffer design * *: End deceleration and impact prevention (optional).
-Corrosion resistant coating: Suitable for marine or chemical environments.
-Position sensing: Install a magnetic switch to detect the endpoint of the travel.
