Exploring the Spring-Return Single-Acting Hydraulic Cylinder For Loading And Unloading
Definition of the Spring-Return Single-Acting Hydraulic Cylinder
Spring-return single-acting oil cylinder is a hydraulic cylinder that utilizes hydraulic oil to extend the piston. When the pressure is released, the built-in spring automatically retracts the piston.
Design and Construction Characteristics
Single-Acting Structure
- Operates in one direction through hydraulic oil pressure
- Return depends on the built-in spring

Spring Selection
- Appropriate spring choice ensures quick and complete reset
Sealing Design
- High-quality sealing materials prevent oil leakage
Strength and Durability
- Material selection considers high pressure and impact resistance
Construction and Assembly Process
The assembly process requires precise component alignment to reduce friction and wear. Strong welding and connections prevent oil leakage under high pressure. Testing guarantees normal operation.
Working Principle
The hydraulic oil extends the piston against the load. The spring mechanism retracts the piston when the pressure is released.
