Airtac SGCD Dual Rod Cylinder SGCD200X80S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X80S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCD Dual Rod Cylinder SGCD200X80S
Delivering 15079 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a piston rod exiting both covers. The twin-rod layout creates a symmetric load path that resists torsional twist, making it ideal for guiding heavy platens or driving two tools at once. It yields a safe working load of roughly 9047 N, which translates to lifting about 769 kg vertically with a 2:1 safety margin.
Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the unit is dimensionally interchangeable per the ISO 15552 mounting interface. Air enters via a G3/4 port, while adjustable 50 mm cushions decelerate the payload at each end. Because the SKU carries the -S suffix, it includes a built-in piston magnet for CMSG, DMSG, or EMSG position switches.

Theoretical Output Force (Ø200mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | 21111 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD200X80S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with equal 15079 N force, keeping cycle times balanced.
Symmetric Platen Lift
Lifts heavy press platens straight up without twisting, using the dual rods to maintain strict parallel alignment.
Dual-End Transfer Pusher
Pushes a workpiece forward while extending a rear cam to trigger a CMSG sensor, sequencing the next conveyor stage.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X80S the Right Cylinder?
This 200 mm bore sits between the 160 mm option (9425 N each way) and the 250 mm model (23562 N), letting you scale thrust precisely. Choose the double-rod configuration when a job demands anti-rotation guidance, twin tooling stations, or a rear-end sensor cam. Mounting hardware includes FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet supports electronic or reed sensing. For any stroke at or above 500 mm, support the rod externally to prevent side-load wear. Remember that the air cushion only decelerates; add an external rod lock or pilot-operated check valve if you need to hold a load securely without live air.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCD Dual Rod Cylinder SGCD200X80S FAQ
It delivers equal force in both directions: 15079 N at 0.5 MPa and 21110 N at 0.7 MPa, with a theoretical max of 3075 kgf at 1.0 MPa. It features a 200 mm bore, 80 mm stroke, G3/4 port, and 50 mm adjustable cushions.
Having a rod extend from both ends provides a symmetric load path that prevents rotation and platen twist. It also allows the rear rod to act as a mechanical cam for CMSG or DMSG sensors, giving you precise end-of-stroke feedback.
