Airtac SGCD Dual Rod Cylinder SGCD250X160
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X160 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 160mm stroke, G1 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 SGCD250X160
Generating 23562 N of equal force in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance the load path completely. Because the rod passes through both covers, the pressure area stays identical on each face, yielding 32986 N at 0.7 MPa and a maximum theoretical output of 4805 kgf at 1.0 MPa. The G1 air port feeds the chamber reliably, while four steel tie rods clamp the aluminum barrel securely to the covers.
This configuration is well-suited for about 14137 N of safe working load, which translates to lifting roughly 1201 kg vertically with a 2:1 safety margin. As a 250 mm bore unit, it uses an NBR front-cover packing and buffer gasket because TPU seals are not available at this size, though a Viton H option extends operation up to 150 C. Note that this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors without switching to the -S variant.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD250X160 Is Used
Twin-Side Pressing Station
Simultaneously forms or stamps two separate panels from a single actuator using both rod ends, ensuring perfectly synchronized pressure.
Balanced Heavy Lift Platform
Raises and lowers a 1200 kg machining fixture with equal push and pull thrust, relying on the symmetric load path to prevent guide bushing wear.
Anti-Twist Indexing Gate
Shifts a massive materials handling barrier without rotational drift, using the dual rods to maintain strict parallel alignment.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X160 the Right Cylinder?
Sitting at the top of the SGCD range, this 250 mm bore provides the highest thrust available, significantly outmuscling the 200 mm option which yields 15079 N at 0.5 MPa. If your application requires less force, stepping down saves space and air consumption, but for maximum equal-both-ways output this size is unmatched. Choose a double-rod design when you need anti-rotation stability, symmetric load distribution, or a rear rod extension to drive a secondary tool or sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since the 160 mm stroke is relatively short for this bore, side-load stress is minimal, but any future deployment exceeding 500 mm should incorporate external guide rails to prevent binding.
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 SGCD250X160 FAQ
It delivers equal force in both directions: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa, with a theoretical max of 4805 kgf at 1.0 MPa. It features a 250 mm bore, 160 mm stroke, a G1 air port, and an M42x2.0 rod thread.
No, a standard double-rod cylinder drifts without live air, as the adjustable 60 mm cushions only decelerate the piston near the end caps. To maintain a vertical position you must add an external rod lock or a pilot-operated check valve.
