The rail-mounted rotating cylinder is a type of
Hydraulic Cylinder designed for installation on a rail. It is widely used in various
#### **1. Product Overview**
The rail-mounted
Rotary Cylinder is a compound
Hydraulic Actuator that integrates linear motion and rotational motion. It ensures high-precision positioning through rail guidance while providing rotational torque output. It is suitable for automated equipment that requires simultaneous push-pull and rotational actions, such as robotic arms, flipping mechanisms, and valve control systems.

#### **2. Core Features**
- **Compound Motion Capability**
- **Linear Stroke**: Hydraulic-driven piston rod extends and retracts linearly (optional double-acting or single-acting).
- **Rotational Torque**: Converts linear motion into rotational motion through internal helical grooves or gear rack structures (rotation angles typically 90°, 180°, or 270°).
- **High-precision Guidance**
- Built-in or external **linear guides** with strong resistance to lateral forces, preventing wear caused by eccentric loading on the piston rod.
- Repeatability positioning accuracy can reach **±0.05mm** (depending on configuration).
- Compact structure
- Integrated design saves installation space and can be directly fixed to the equipment base through guide rail bolts.
- **High Load Adaptability**
- Rotational torque range: **50Nm to 2000Nm** (customizable for higher torque).
- Linear thrust: **5kN to 100kN** (depending on cylinder diameter and pressure).
- Environmental adaptability
- Sealing parts can be made of high-temperature resistant materials (-30℃ to 150℃) or corrosion-resistant materials (such as FKM) as options.

#### **3. Typical Application Scenarios**
- **Automated Production Lines**: Workpiece flipping, clamping and synchronous rotation operations (such as in automotive welding fixtures).
- **Valve Control**: Opening and closing of high-pressure pipeline valves and position locking.
- **Material Handling**: Integrated grasping, rotating and placing actions of mechanical arms.
- **Specialized Equipment**: Drive for folding arms and rotating platforms in construction machinery.
