When selecting actuators for industrial equipment, understanding the difference between high torque rotary cylinders and linear hydraulic cylinders helps make better decisions based on motion requirements.
Product Overview
High torque rotary cylinders generate rotational movement, while linear hydraulic cylinders produce straight-line motion. The choice depends on whether the application requires rotation or linear pushing and pulling force.
Core advantages of high torque rotary cylinders include direct rotational output, compact design for rotation tasks, and good torque-to-size ratio.
Technical Parameters
| Parameter | High Torque Rotary Cylinder |
|---|---|
| Motion Type | Rotational |
| Maximum Torque | Up to 130000 Nm |
| Rotation Angle | 90 degree to 360 degree |
| Operating Pressure | Up to 210 bar |
Working Principle and Structure
High torque rotary cylinders use hydraulic pressure acting on internal pistons or vanes to create rotational torque on a central shaft. The structure includes a robust housing, precision components, bearings, and sealing systems designed for continuous rotational tasks.
Core Advantages
1. Direct Rotational Motion
Provides rotation without needing additional mechanical linkages.
2. Compact Design
Offers good torque in a relatively small package for rotation applications.
3. Precise Angle Control
Supports accurate positioning in automated systems.
4. High Torque Capacity
Suitable for heavy rotational loads in port and industrial equipment.
5. Lower Mechanical Complexity
Reduces the need for extra linkages in rotational applications.
Typical Application Scenarios
Port Cranes
Used for boom rotation and load positioning where rotational movement is required.
Промислова автоматизація
Applied in rotation stations for parts handling and assembly processes.
Будівельне обладнання
Supports rotation of attachments on excavators and drilling rigs.
Selection Guide
When deciding between rotary and linear cylinders, consider:
- Type of motion needed (rotation or linear)
- Available installation space
- Required force or torque
- Precision requirements
- Maintenance accessibility

Часті запитання
When should I choose a rotary cylinder instead of a linear one?
Choose rotary cylinders when your application requires rotational movement rather than straight-line motion.
Can rotary cylinders fully replace linear cylinders?
In some cases yes, but it depends on the motion type and mechanical design of your equipment.
