Expanding on the Spring-Return Single-Acting Hydraulic Cylinder for Tensioning Applications
Defining 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 pressure is released, the built-in spring automatically retracts the piston.
When designing a spring-return single-acting hydraulic cylinder, several key characteristics need to be considered:
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
- Ensures system efficiency and safety
Strength and Durability
- Material selection must withstand high pressure and impact
- Usually made of high-strength steel
Working Principle of Spring-Return Single-Acting Hydraulic Cylinder
The single-acting mechanism of the hydraulic cylinder pushes the piston outward when hydraulic oil is pumped in. The spring mechanism then retracts the piston back to its initial position when pressure is released.


Spring-Return Single-Acting Hydraulic Cylinder Types
There are three main types of spring-return single-acting hydraulic cylinders, each with specific configurations tailored to different applications.
