Design Features
The design of threaded head welded hydraulic cylinders incorporates several key features that enhance their durability and functionality:
All-Welded Steel Structure
The strong all-welded steel construction of these cylinders ensures robustness and resistance to mechanical stresses, making them suitable for heavy-duty applications.
Threaded End Cap Design
The threaded end cap design allows for easy and safe installation of the cylinder, providing a secure connection point for hydraulic lines and fittings.

High-Grade Materials
These cylinders are crafted from high-quality materials and undergo advanced manufacturing processes to guarantee superior performance and longevity.
Seamless Integration
The seamless integration of the cylinder block and end cap ensures excellent structural integrity, minimizing the risk of leaks or failures during operation.
Working Principle
Threaded head welded hydraulic cylinders operate by utilizing hydraulic pressure from an external source to generate mechanical force. They are typically connected to a hydraulic pump station or accumulator to receive the necessary fluid power for movement.
Types and Configurations
There are three main types of threaded head welded hydraulic cylinders available, each tailored to specific application requirements:
Single-Acting Cylinders
Single-acting cylinders utilize hydraulic pressure in one direction to extend or retract the piston rod, making them ideal for applications that require linear motion in one direction.
Double-Acting Cylinders
Double-acting cylinders use hydraulic pressure in both directions to move the piston rod back and forth, offering greater flexibility and control in various industrial tasks.
Telescopic Cylinders
Telescopic cylinders feature multiple nested stages that extend and retract, providing extended stroke lengths and compact design for space-restricted applications.
