Working Principle

The CDJ2RA10-125Z-B utilizes a double-acting cylinder design. When compressed air enters the non-rod side, the air pressure pushes the piston, generating thrust to extend. When compressed air enters the rod side, the air pressure pushes the piston to retract. The reciprocating motion of the cylinder is achieved by controlling the direction of compressed air flow via a solenoid valve. The built-in magnetic ring allows for position detection in conjunction with magnetic switches. The cushioning device absorbs impact energy as the piston approaches the end of the stroke, slowing the piston to a stop and preventing or reducing impact on the cylinder head.

Typical Application Scenarios

1. Industrial Automation Production Lines Used in automated production lines for automotive manufacturing, electronic device production, etc., for pushing, positioning, clamping, and transporting workpieces, enhancing production efficiency and product quality.
2. Packaging Machinery Controls actions such as material conveying, sorting, and marking in packaging machines. The cylinder enables flexible grasping and positioning of different materials, ensuring precision and stability in the production process.
3. Robotics Technology Serves as an end effector for robots, working in tandem with robotic arms to grasp, position, and place workpieces, improving robotic motion accuracy and efficiency.
4. Precision Manufacturing Equipment Used in equipment for semiconductor manufacturing and precision machining to control the motion accuracy of pneumatic actuators, ensuring process stability and repeatability, and enhancing product quality.

Installation and Usage Considerations

1. Installation Requirements The cylinder should be installed on a flat, stable base to ensure stable operation. Before installation, verify that the air source pressure meets the 0.06–0.7 MPa requirement and ensure the air source is clean. During installation, avoid subjecting the piston rod to eccentric or lateral loads; ensure the load’s motion direction aligns with the piston rod axis.
2. Operating Environment The operating temperature range is -10–60°C; avoid use in excessively high or low temperatures. Maintain appropriate relative humidity levels to prevent moisture from affecting equipment lifespan. The operating medium should be filtered through a 40 μm or finer filter before use.
3. Regular Maintenance Regularly inspect the cylinder’s connecting pipes and valves to ensure no leakage. Periodically clean the cylinder surface to maintain cleanliness. Regularly check the cylinder’s performance to ensure long-term stable operation.
4. Safe Operation Ensure the equipment is properly grounded before operation to prevent electric shock hazards. Avoid contact with moving parts during operation to prevent injuries. In case of equipment malfunction, stop operation immediately and have it repaired by professionals. Always depressurize before installation to prevent injuries from high-pressure medium discharge.
