Expanded Introduction to Spring-Return Single-Acting Hydraulic Cylinder
Spring-Return Single-Acting Hydraulic Cylinder is a type of hydraulic cylinder that utilizes hydraulic oil to expand the piston. When pressure is released, an internal spring automatically retracts the piston.
Design and Construction Characteristics
Single-Acting Structure
- Operates in one direction using hydraulic oil pressure
- Return is dependent on the built-in spring
Spring Selection
- Appropriate spring choice ensures quick and complete reset
Sealing Design
- Utilizes high-quality sealing materials to 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, especially the piston and cylinder block, to minimize friction and wear.
Welding and Connection
- Strong welding and mechanical connections prevent oil leakage
Testing and Debugging
- Strict pressure and functional testing ensures proper operation
Working Principle
The single-acting mechanism extends the piston when hydraulic oil is pumped in and retracts it when pressure is released, using the spring mechanism.
Types and Configurations
There are three different types of Spring-Return Single-Acting Hydraulic Cylinders, each with unique configurations suitable for various applications.
