Spring-Return Single-Acting Hydraulic Cylinder

Introduction to the Keywords

Spring-Return Single-Acting Hydraulic Cylinder is a hydraulic cylinder that utilizes hydraulic oil to expand the piston. When the pressure is released, the built-in spring automatically retracts the piston.

Design and Construction Characteristics

• Single-Acting Structure: Hydraulic oil pressure in one direction, return by built-in spring.
• Spring Selection: Appropriate spring for quick and complete reset.



• Sealing Design: High-quality materials to prevent oil leakage.
• Strength and Durability: High-strength steel for high pressure.

Construction and Assembly

The assembly process requires precise docking of components, strong welding and mechanical connections, and rigorous testing for normal operation.

Working Principle

When hydraulic oil is pumped, the piston extends, and upon pressure release, the spring mechanism retracts the piston.

Types and Configurations

There are three types of spring-return single-acting hydraulic cylinders with various configurations for specific applications.

Key Benefits

• Safety – Automatic reset reduces the risk of accidents.
• Simplicity – Easy design for maintenance and repair.
• Cost-Effective – Economical alternative to double-acting cylinders.
• Flexible Operation – Strong adaptability to various applications.
