Working Principle

During tension and contraction, bidirectional hydraulic fluid flow enables independent extension and contraction movement, providing precise control and efficiency in various applications.

Types and Configurations

  • Standard single-acting cylinder
  • Telescopic single-acting cylinder
  • Differential single-acting cylinder

Internal Components and Structure

The single-acting telescopic hydraulic cylinder features a multistage structure with a piston and chamber, special sealing, guiding, and retracting mechanisms for enhanced performance and durability.


  • Precise positioning
  • Force-generating properties
  • Stability and rigidity
  • Responsiveness


Single-acting telescopic cylinders are widely used in industries such as material handling, construction equipment, agricultural machinery, and special equipment due to their reliability and efficiency.

Selection Factors

Considerations such as size range, inner diameter, stroke length, material selection, durability, integrated functions, and installation options are crucial when choosing a single-acting telescopic hydraulic cylinder.


  • Regular inspection of seals and bushings
  • Proper hydraulic oil maintenance
  • Contamination control

Installation Steps

Proper installation of the single-acting telescopic hydraulic cylinder is essential for optimal performance. Follow the recommended steps to ensure a seamless setup.

Fault Diagnosis and Solutions

Common problems such as leakage, insufficient force, or unstable motion can be effectively diagnosed and resolved with proper troubleshooting techniques and preventive measures.
