Expanding the Definition of Spring-Return Single-Acting Hydraulic Cylinder
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.
Design and Construction Features
- Single-Acting Structure: Operates with hydraulic oil pressure in one direction, return function depends on the built-in spring.
- Spring Selection: Appropriate spring choice ensures quick and complete reset after pressure release.
- Sealing Design: High-quality seals prevent oil leakage, ensuring system efficiency and safety.
- Strength and Durability: Material selection considers high pressure and impact resistance, typically high-strength steel.

Construction and Assembly Process

The assembly process requires precise component alignment, especially piston and cylinder block coordination, to reduce friction and wear. Strong welding and mechanical connections prevent oil leakage under high pressure. Strict testing ensures normal operation post-assembly.
Working Principle
The hydraulic cylinder extends when fluid enters, pushing the piston against the load. Upon pressure release, the spring mechanism retracts the piston to its initial position.
Types and Configurations
Spring-return single-acting hydraulic cylinders come in three different types with unique configurations, each suitable for specific applications.
Key Benefits
- Safety – Automatic Reset
- Simplicity – Simple Design
- Cost-Effective – Economical
- Flexible Operation – Strong Adaptability
