Single & Double Acting Cylinders
Bore size, stroke, mounting type, and working pressure can be adapted for your exact equipment, including agriculture, construction, and industrial machinery.
Hydraulic Cylinder Manufacturer in China
Custom Hydraulic Cylinders
Built for Real Working Conditions
Whether you need a replacement cylinder or a full OEM batch, we engineer durable, precise, and well-tested cylinders for excavators, trailers, presses, farm machines, and industrial systems.
Supported Cylinder Types
We customize cylinders for both standard and demanding applications across industrial, agricultural, and mobile machinery.
Double Acting
Moves under pressure in both directions for precise control and stable output.
Single Acting
Operates in one direction with pressure, ideal for lifting or pushing tasks.
Telescopic
Multi-stage extended stroke cylinders for dump trucks, trailers, and lifting units.
Tie Rod
Strong, repairable structure widely used in industrial and manufacturing equipment.
Welded
Compact, durable design with welded heads—ideal for mobile machinery.
Heavy Duty
Reinforced structures for harsh pressure cycles in mining and construction.
Steering Cylinders
Built for accurate steering control in tractors, loaders, and mobile equipment.
Special Purpose Cylinders
Custom-built for unique machine layouts, extreme temperature, or special loads.
What You Can Customize
Design hydraulic cylinders that match your machine and working conditions. Adjust size, pressure level, mounting style, and protection so each cylinder fits your project both mechanically and economically.
Size
Bore & Rod Diameter
Choose bore and rod sizes to match your load and speed. We machine barrels and rods to tight tolerances for smooth motion and stable force output.
Travel
Stroke Length
Set the exact stroke you need for lifting, pushing, steering, or clamping. Short, medium, and long strokes are available for different machine layouts.
Mounting
Mounting Types
Front flange, rear flange, clevis, trunnion, spherical bearings, foot mounts and other custom options to match your existing brackets and pins.
Pressure
Working Pressure
Configure cylinders for low, medium, or high-pressure systems. Wall thickness, material grade, and seal selection are matched to your pressure range.
Connection
Ports & Thread Types
Pick BSP, NPT, SAE or custom port styles to match your hoses and fittings. Port size, position, and orientation are set according to your manifold or piping layout.
Protection
Coatings & Colors
Select painting systems, primers, and colors that match your brand and working environment, from standard industrial paint to stronger anti-corrosion layers.
Hydraulic Cylinder Highlights
We focus on stable quality rather than fancy marketing. Every cylinder is built for daily work: heavy loads, dusty yards, long transport, and demanding customers who cannot afford machine downtime.
Telescopic and Custom Stroke
Multi-stage designs for dump trucks, tipping trailers, lifting platforms, and narrow installation spaces where long stroke is needed but space is limited.
Durable Rod and Sealing System
Chrome or induction hardened rods, quality seals, and proper surface treatment help your cylinder keep working even under dusty, muddy, or salty conditions.
Flexible Mounting and Ports
Clevis, trunnion, flange, eye, or custom mounting; port styles matched with your local hose and fitting standards to make installation easier.
Tell us your cylinder size, working pressure, and application so we can match a proper cylinder design for you.
Typical Cylinder Technical Outline
Below is an example of a working range for a general-purpose double-acting cylinder. We adapt the parameters to your machine.

We will not force you to adopt a fixed catalog model, but rather adjust key parameters based on your equipment and actual market requirements. When you send us your drawings, we will manufacture the most satisfactory product according to your specifications.
Share your current cylinder parameters so we can confirm if they match your working pressure and load.

Let us know which industry you are in so we can share similar cases and cylinder designs we made for others.
Compare Cylinder Options
Different projects need different cylinder concepts. This table gives a simple view of what you can expect.
| Type | Best For | Main Advantages | Things to Note |
|---|---|---|---|
| Single Acting | Simple lifting, gravity return | Lower cost, simpler plumbing | Not suitable where controlled retraction is needed |
| Double Acting | Most mobile and industrial equipment | Controlled movement in both directions | Requires two lines and proper valve choice |
| Telescopic | Dump trucks, tipping trailers | Long stroke with compact retracted length | Higher technical requirements and careful use |
| Tie-Rod | Industrial presses, factory equipment | Easy to service, standard interfaces | Not always suitable for very harsh outdoor use |

How We Ensure Compatibility
Each cylinder is checked against your machine details so ports, mounting, stroke, and pressure range match your real working conditions.
Replace Original Cylinder
We cross-check your photos, samples, and drawings so the new cylinder can directly replace the original unit on your machine.
Build New Design
For new machines, our engineers design cylinders based on your structure, stroke, load, and duty cycle targets.
Match Ports & Mounting
Port threads, locations, and mounting styles are aligned with your hoses, brackets, pins, and frames to avoid rework on site.
Confirm Working Pressure
We verify system pressure, safety margin, and cylinder wall thickness so the design stays safe in real operation.
Sample Checking
Sample cylinders can be tested on your machine first, and any feedback is used to fine-tune the next batch.
Dimensional Verification
Key dimensions such as pin size, stroke, retracted length, and mounting distances are measured and recorded before shipment.
