Product Overview
What Is a Welded Hydraulic Cylinder?
A welded hydraulic cylinder is a cylinder where the barrel and end caps are permanently welded together, forming a single rigid body that resists bending and twisting during heavy work.
Key Characteristics
- Compact structure for machines with limited installation space.
- Strong welded joints that handle shock, vibration, and side loads.
- High load capacity and long service life under continuous duty.
Welded vs Tie-Rod Hydraulic Cylinders
- Welded cylinders use a smooth barrel with welded ends, while tie-rod cylinders use external tie rods to hold end caps in place.
- Welded designs usually offer a smaller outer size for the same bore and stroke, which saves space on compact equipment.
- Welded cylinders handle vibration and side loads better in mobile and heavy-duty applications, such as construction and mining machines.

Welded Hydraulic Cylinder FAQ
Simple answers to common questions about welded hydraulic cylinders.
What is a welded hydraulic cylinder?
A welded hydraulic cylinder is built with the end caps welded directly to the barrel,
creating a compact, strong, and highly durable structure ideal for heavy-duty applications.
Where are welded cylinders commonly used?
They are widely used in excavators, loaders, mining trucks, agricultural machinery,
industrial presses, and any equipment requiring high pressure and strong vibration resistance.
What makes welded cylinders stronger than tie-rod cylinders?
The welded construction eliminates tie rods and uses fully welded joints,
which increases rigidity, reduces size, and improves performance under shock and vibration.
Can welded hydraulic cylinders be customized?
Yes, we support custom bore size, stroke length, mounting type, pressure rating,
coatings, seals, and port positions based on your machine’s requirements.
How long is the lead time for welded cylinders?
Standard welded cylinders ship in 20–30 days.
Custom cylinders require 35–45 days depending on complexity and quantity.
Do welded hydraulic cylinders require maintenance?
The cylinder itself requires minimal maintenance. Regular checks should focus on seals,
weld integrity, lubrication, and contamination inside the hydraulic system.
