1. Double the output force: For the same cylinder bore, the output thrust is approximately twice that of a single-rod cylinder, allowing for higher thrust in confined spaces.
2. Integrated guidance and anti-rotation: The dual-rod design constrains the load and prevents piston rod rotation; it withstands lateral forces and torsional loads, eliminating the need for external guide rails and simplifying the mechanism.
3. Compact structure with multi-face mounting holes: Mounting is possible on the bottom, sides, or front plate, offering flexible installation options and saving equipment space.
4. Built-in cushioning pads: These absorb impact at the end of the stroke.

Twin Rod Cylinder: Basic Parameters for Selection

A dual-rod cylinder is a pneumatic actuator featuring two parallel piston rods that move in synchronization;

it is essentially the integration of two single-rod cylinders into a single aluminum alloy body.

Driven by compressed air, the two piston rods extend and retract together,

making this one of the most commonly used guided cylinders in automation.

Twin Rod Cylinder: Frequently Asked Questions

MYFEQD offers a comprehensive range of Xi lanh hai thanh solutions.

Our pneumatic actuators comply with the technical standards of major global brands,

providing quick solutions for model selection across various industrial

pneumatic systems.

Difference from a single-rod cylinder?

Anti-rotation, side-load capable; the double-piston version delivers about twice the thrust of a single rod at the same bore size.

CXS/CXSM/CXSL, TR/TN.

Choose bore by thrust with over 50% safety margin; choose stroke by travel distance, plus 5–10 mm at both ends.

Slide bearing : heavy load and impact; ball bearing : high speed, precision and frequency.

Flat mounting surface (flatness ≤0.05 mm); rods must not be twisted, forced or scratched.

Yes. Exhaust (meter-out) flow control is recommended for stable movement.

Standard models are pre-greased and non-lube; no extra oil is needed.

Check air pressure, solenoid valve signal, blocked air lines and jammed load.

Jerky or creeping movement?

Switch to meter-out control; check misalignment, overload and worn guides.

Rod leakage: replace rod seal /wiper; cover leakage: tighten screws or replace seals.

Check low pressure, internal piston-seal leakage and undersized bore.

Reduce speed; check cushioning, lubrication and bearing wear.

Series, bore, stroke, bearing type, magnet option, thread specs and special working conditions.

Yes. Vertical loads require a 3-position closed-center valve, drop-prevention valve or mechanical lock.

No. Both rods are fixed to one plate and move synchronously.

Retract the rods, apply anti-rust oil to exposed rods, seal ports and store in a dry, ventilated place.
