Enhancing Safety and Functionality: Self-Locking Welded Hydraulic Cylinders in Aerospace Manufacturing
Introduction
Hydraulic cylinders play a crucial role in the machinery industry, providing the necessary power to move heavy loads with precision and control. Among these, self-locking welded hydraulic cylinders have become increasingly popular due to their unique design features and safety mechanisms.

Design and Construction Characteristics
- Welded Structures: High strength welding ensures overall strength and tightness, capable of withstanding high pressure and heavy loads.
- Integrated Design: The absence of removable connections reduces the risk of leakage and increases reliability.
Self-Locking Mechanism
- Mechanical Self-Locking: Prevents accidental sliding or displacement through a mechanical structure when the cylinder is at rest.
- Hydraulic Self-Locking: Ensures hydraulic oil cannot flow in reverse under load, maintaining stable cylinder position.

Working Principle
The self-locking welded hydraulic cylinder operates by utilizing mechanical or hydraulic locking mechanisms to prevent accidental movement, providing added safety and functionality in aerospace manufacturing applications.
Types and Configurations
There are three main types of self-locking welded hydraulic cylinders, each offering specific configurations tailored to different aerospace manufacturing needs.
