Airtac SGCD Dual Rod Cylinder SGCD200X125
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X125 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 125mm 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 SGCD200X125
Delivering 15079 N of equal output force in both directions at 0.5 MPa, this large-bore tie-rod cylinder uses a twin-rod design to balance the load path perfectly. The G3/4 port feeds a 200 mm bore that 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 high structural rigidity. Because the piston rod passes through both covers, it provides inherent anti-twist guidance and allows you to drive two separate tools simultaneously. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this range up to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD200X125 Is Used
Twin-Tool Stamping
Drives two separate forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized press cycles.
Symmetric Diverting
Pushes product from the center of a belt line outward using both rod ends, keeping the load path balanced and preventing binding.
Anti-Rotation Lifting
Raises and lowers heavy 769 kg platens without twisting, relying on the inherent guidance of the dual-rod assembly.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X125 the Right Cylinder?
This 200 mm bore sits between the 160 mm option (9425 N each way) and the 250 mm model (23562 N each way). Choose the double-rod configuration when your mechanism requires anti-rotation stability, symmetric load distribution, or a rear-end sensor cam. Mounting hardware includes FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. For any stroke length over 500 mm, always use external guide rails to prevent side-load wear on the rod seals.
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 SGCD200X125 FAQ
The double-rod design yields equal force both ways: 15079 N at 0.5 MPa and 21110 N at 0.7 MPa. The theoretical maximum is 3075 kgf at 1.0 MPa. It operates on G3/4 ports with a 40 mm rod.
No, the air cushions only decelerate the piston near the stroke ends; they do not hold load on air loss. You must use an external rod lock or pilot-operated check valve for holding. Additionally, this SKU lacks the -S magnet, so it cannot accept CMSG or DMSG sensors.
