Featured Rotary Cylinders
Hydraulic Rotary Actuators
High-torque rotary cylinders designed for demanding industrial and mobile applications.
Custom Rotary Cylinders
Tailored solutions with custom torque, angle, mounting, and shaft configurations.
Helical Rotary Actuators
Compact, high-torque helical actuators ideal for space-constrained applications.
Rotary Cylinder Structure
Housing / Body
High-strength steel or aluminum housing that contains internal components and withstands high pressure.
Output Shaft
The rotating shaft that delivers torque to the application. Available in various configurations.
Piston & Vane / Helical Mechanism
Converts linear hydraulic force into rotational motion through piston, vane, or helical gear design.
Seals & Bearings
High-performance seals prevent leakage and bearings ensure smooth, long-lasting rotation.
How Hydraulic Rotary Actuators Work
Hydraulic rotary actuators convert hydraulic pressure into controlled rotational motion. Pressurized oil enters the actuator and acts on pistons, vanes, or helical gears, generating torque that rotates the output shaft. The direction and angle of rotation are precisely controlled by the hydraulic system, making them ideal for applications requiring high torque and accurate positioning.

Frequently Asked Questions
Technical & Product Selection
1. What is the difference between a rotary cylinder and a hydraulic rotary actuator?
A rotary cylinder converts pressure into rotational motion. A hydraulic rotary actuator is a high-torque type designed for precise angular positioning in heavy-duty applications.
2. How do I choose the correct torque rating?
Torque depends on load, rotation angle, system pressure, and duty cycle. Our team can help calculate the right specification for your application.
3. Do you offer both hydraulic and pneumatic versions?
Yes. We manufacture both hydraulic rotary actuators and pneumatic rotary cylinders.
4. What rotation angles are available?
Standard angles include 90°, 180°, and 360°. Custom angles are also available.
5. Are they suitable for continuous rotation?
Most models are for limited-angle (oscillating) motion. We can provide solutions for continuous rotation requirements.
Manufacturing & Quality
1. Where are your products manufactured?
In advanced facilities with modern CNC machining and strict quality control, supported by our strong production strength.
2. What testing do you perform?
Every unit undergoes pressure testing, functional testing, and final inspection before shipment.
3. Can you produce custom rotary cylinders?
Yes. We have extensive experience in custom manufacturing according to customer drawings and requirements.
4. What is the typical lead time?
We provide accurate lead times in every quotation based on product type and customization level.
5. Can you provide test reports?
Yes. Material certificates and test reports are available upon request.
Pricing, Ordering & After-Sales
1. How competitive are your prices?
We offer competitive pricing thanks to efficient production processes and strong manufacturing capabilities.
