Airtac SGCD Dual Rod Cylinder SGCD200X75
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X75 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 75mm 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 SGCD200X75
Delivering 15079 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder uses a symmetric load path to eliminate uneven piston wear. The G3/4 port feeds a single piston carrying a 40 mm rod out both covers, generating identical push and pull forces. Four steel tie rods clamp the aluminum barrel for high structural rigidity, while the genuine ISO 15552 mounting interface ensures easy fixture interchangeability.
With a 15079 N output, you get a safe working load of roughly 9047 N, which translates to lifting about 769 kg vertically with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, though a Viton H option extends heat resistance up to 150 C. Note that this specific SKU lacks a magnet, so it cannot host CMSG or DMSG sensors without upgrading to the -S variant.

Theoretical Output Force (Ø200mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | 21111 N |
| Max (@1.0 MPa) | 3204 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD200X75 Is Used
Twin-Spindle Pressing
Drives two opposing forming tools simultaneously using the equal push and pull force to maintain parallel contact on heavy stamping assemblies.
Symmetric Diverting Gate
Uses the through-rod design to actuate a routing flap from the rear while the front end carries a mechanical cam for position feedback.
Balanced Vertical Lift
Lifts approximately 769 kg of raw material in a guided hoist, leveraging the equal both-ways force to prevent gravity-induced drift during extension.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X75 the Right Cylinder?
When sizing this family, the neighboring 160 mm bore provides 9425 N each way, while the larger 250 mm bore steps up to 23562 N. Choose a double-rod configuration when your application demands anti-rotation stability, twin-tool driving, or a rear-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this 75 mm stroke is short, side-load guidance is minimal, but any stroke over 500 mm requires external load bearings to prevent binding. Remember that a plain cylinder drifts without live air, so integrate an external rod lock for suspended loads.
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 SGCD200X75 FAQ
Because it is a double-rod cylinder, the force is equal both ways using the rod-side area. It generates 15079 N at 0.5 MPa and 21110 N at 0.7 MPa, with a theoretical maximum of 3075 kgf at 1.0 MPa. The air port is G3/4 and the rod-end thread is M36x2.0.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG, or EMSG magnetic switches. Without the -S option, the cylinder cannot host internal sensors, so you would need external mechanical limit switches.
