Exploring the Spring-Return Single-Acting Hydraulic Cylinder
Definition of the Spring-Return Single-Acting Hydraulic Cylinder
The Spring-Return Single-Acting Hydraulic Cylinder is a hydraulic cylinder that utilizes hydraulic oil to expand the piston. When the pressure is released, the built-in spring automatically retracts the piston.
This mechanism ensures efficient operation and safety in various applications.
Design and Construction Characteristics
Single-Acting Structure
- Hydraulic oil pressure operates in one direction
- Return function is dependent on the built-in spring
Spring Selection
- Appropriate spring choice for quick and complete reset
Sealing Design
- High-quality sealing materials to prevent oil leakage

Strength and Durability
- Material selection for high pressure and impact resistance
Construction and Assembly Process
Assembly precision for reduced friction
Strong welding and connections for oil leakage prevention
Thorough testing for operational reliability
Working Principle
The hydraulic oil pushes the piston against the load, and when released, the spring mechanism returns the piston to its initial position.
Types and Configurations
Various types available with specific configurations for different applications.
Key Benefits
- Safety with automatic reset
