Understanding Single-Acting Telescopic Hydraulic Cylinder

Single-acting telescopic hydraulic cylinder is a type of hydraulic cylinder that operates in one direction, utilizing fluid pressure to extend the cylinder. It is commonly used in various industries for its unique design and functionality.

Design Principle and Composition

  • The single-acting telescopic hydraulic cylinder consists of a cylinder, piston rod, seals, and hydraulic oil.
  • The telescopic joint comprises internal and external stages that allow for smooth extension and retraction.

Working Principle

The single-acting telescopic hydraulic cylinder operates by allowing hydraulic fluid to flow bidirectionally during tension and contraction, enabling independent extension and contraction movements.


  • Precise positioning and force generation
  • Stability and rigidity
  • Responsiveness

Types and Configurations

There are three main types of single-acting hydraulic cylinders, each with its unique configuration and applications.

Internal Components and Multistage Structure

The internal components of a single-acting telescopic hydraulic cylinder include a piston, chamber, special sealing, guiding, and retracting mechanisms.

Industry Applications
