Expanded 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 Characteristics
- Single-Acting Structure: Only operates in one direction through hydraulic oil pressure, with return depending on the built-in spring.
- Spring Selection: Choosing the right spring ensures quick and complete reset after pressure release.
- Sealing Design: High-quality seals are essential to prevent oil leakage and ensure system efficiency.
- Strength and Durability: Materials selected need to withstand high pressure and impact, 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. Welding and mechanical connections should be strong to prevent oil leakage under pressure. After assembly, rigorous pressure and functionality testing ensures proper operation.

Working Principle of Spring-Return Single-Acting Hydraulic Cylinder
The cylinder operates with hydraulic oil pushing the piston outward against the load. When pressure is released, the spring mechanism retracts the piston to its initial position.
