Exploring the Functionality of Spring-Return Single-Acting Hydraulic Cylinder Components
Introduction to Spring-Return Single-Acting Hydraulic Cylinder

Spring-return single-acting oil cylinder is a hydraulic cylinder that utilizes hydraulic oil to expand the piston. When pressure is released, the integrated spring automatically retracts the piston.
Design and Construction Characteristics
- Single-Acting Structure: Hydraulic oil pressure works in one direction, while the return depends on the built-in spring.
- Spring Selection: Choosing the right spring ensures quick and complete reset.
- Sealing Design: High-quality materials prevent oil leakage and ensure system efficiency.
- Strength and Durability: Materials must withstand high pressure and impact, typically high-strength steel.
Construction and Assembly Process
- Assembly Precision: Components must be precisely aligned to reduce friction and wear.
- Welding and Connection: Strong welds and connections prevent oil leakage under pressure.
- Testing and Debugging: Pressure and functional tests are crucial for normal operation.
Working Principle
The hydraulic cylinder extends when oil enters, pushing the piston against the load. When pressure is released, the spring mechanism retracts the piston.
