Principe de fonctionnement et structure
High torque rotary cylinders convert hydraulic pressure into rotational motion through internal pistons or vanes that drive a central shaft. The structure includes a heavy-duty housing, precision-machined components, reinforced bearings, and marine-grade sealing systems. Proper sizing ensures the cylinder can handle the required torque without excessive stress on components.

Provides accurate positioning even under heavy load conditions.
3. Robust Construction
Built to withstand continuous heavy loads and vibration in demanding environments.
4. Safety and Reliability
Properly sized cylinders reduce stress on components and improve operational safety.
5. Customization for Heavy Loads
Can be tailored in torque, angle, and mounting to match specific heavy load applications.
6. Long-Term Cost Efficiency
Correct sizing helps avoid premature wear and reduces long-term maintenance costs.
Savoir-faire en matière de structure et de matériaux
These cylinders use heavy-duty alloy steel housing with precision-machined internal components. High-strength bearings and marine-grade seals are essential for handling heavy loads. Proper sizing ensures the structure can manage the required torque without excessive stress on bearings and seals.
Scénarios d'application typiques
Port Cranes
Used for rotating heavy loads during cargo handling. Correct sizing ensures stable torque delivery without overloading the cylinder.
Systèmes de couvercle de trappe
Requires reliable rotation under heavy loads. Proper sizing helps maintain performance and safety during operation.
Heavy Industrial Equipment

Guide de sélection
When sizing a high torque rotary cylinder for heavy load applications, confirm the following:
- Maximum torque required including safety margin (typically 1.5x or higher)
- Required rotation angle
- Operating pressure of the hydraulic system
- Load characteristics (static vs dynamic loads)
- Environmental conditions (temperature, corrosion risk)
- Mounting method and structural support
- Expected duty cycle and continuous operation time
Correct sizing helps ensure safe operation and reduces the risk of premature failure under heavy loads.

Foire aux questions
How do I calculate the required torque for heavy loads?
Calculate the maximum load moment and add a safety margin (commonly 1.5 times or higher) to account for dynamic conditions.
What happens if a cylinder is undersized?
Undersized cylinders can experience excessive stress, leading to premature wear, leakage, or failure under heavy loads.
Can oversizing cause problems?
Oversizing is generally safer but may increase cost and weight. Proper calculation helps find the right balance.
