The PZ/PZJ Series Dual Rod Cylinder is a guided pneumatic actuator designed for applications requiring accurate linear movement and reliable anti-rotation performance. Featuring parallel piston rods connected by a yoke structure, it provides enhanced stability, precise positioning, and improved resistance to side loads. Available with plain-bearing or recirculating ball bearing guides, the cylinder is ideal for automation equipment, transfer systems, positioning units, and industrial handling applications where smooth and repeatable motion is essential.
The PZ/PZJ Series Dual Rod Cylinder combines a parallel rod design with an integrated guide system to deliver stable and accurate linear motion. The through-type piston rod structure effectively prevents unwanted rotation while maintaining excellent rigidity during operation. Designed for modern automation equipment, the cylinder supports precise positioning and smooth movement even under offset loads and repetitive working conditions.

The dual rod arrangement provides enhanced rigidity compared with conventional single-rod cylinders. By distributing forces across two parallel guide rods, the cylinder maintains alignment accuracy and minimizes deflection caused by eccentric loads. This makes the PZ/PZJ Series particularly suitable for positioning, pushing, clamping, and transferring tasks where motion consistency directly affects production quality.
The availability of both plain-bearing and ball-bearing guide versions allows users to select the most suitable solution based on load, speed, and precision requirements.
● Automated assembly equipment
● Pick-and-place systems
● Workpiece positioning devices
● Clamping and pressing mechanisms
● Packaging and conveying machinery
● Electronic component handling
● Inspection and testing equipment
● Material transfer systems
● Industrial automation production lines
With its guided structure, anti-rotation capability, and versatile mounting options, the PZ/PZJ Series Dual Rod Cylinder provides a dependable solution for precise linear motion control across a wide range of industrial automation applications.
