DPZ Series: Precision Twin-Rod Cylinders for Non-Rotating Accuracy


The DPZ series is a high-performance twin-rod (dual-rod) pneumatic cylinder designed for applications where rotation must be prevented and lateral loads are significant. By using two parallel piston rods, the DPZ series provides double the output force of a standard cylinder while maintaining a compact, low-profile footprint. It is the industry standard for high-precision guiding and sorting tasks.

Key Technical Features & Engineering Highlights

  • Superior Non-Rotating Accuracy: The dual-rod construction inherently prevents the piston rod from rotating, ensuring that end-effectors or tooling remain perfectly aligned throughout the stroke.

  • High Lateral Load Capacity: The twin-rod design, supported by high-precision guide bushes or ball bearings, allows the cylinder to handle much higher side loads compared to traditional single-rod cylinders.

  • Double Output Force: With two pistons working in tandem, the DPZ series delivers nearly twice the thrust and pull force of a single-bore cylinder of the same width.

  • Compact & Low-Profile Design: Its flat, rectangular body allows for installation in narrow spaces where height is limited, making it ideal for modern, compact machine frames.

  • Adjustable Stroke Options: Many models include an adjustable stroke bolt, allowing for fine-tuning of the extension to match precise application requirements.

  • Magnetic Sensing Integration: The cylinder body features integrated slots for magnetic sensors (auto-switches) for easy position feedback and PLC integration.
