Airtac SGCD Dual Rod Cylinder SGCD125X160S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X160S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm stroke, G1/2 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 SGCD125X160S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod layout to equalize force. The G1/2 port feeds a 125 mm bore that generates identical push and pull output, letting you drive tooling from either end without re-engineering your pressure settings. Its four steel tie rods clamp the aluminum barrel securely to the covers, ensuring structural rigidity under heavy cyclic loads.
With a built-in piston magnet, the -S suffix supports CMSG, DMSG, and EMSG electronic or reed switches for end-of-stroke confirmation. This symmetric load path resists torsional twist, providing safe working loads around 3440 N or roughly 292 kg of vertical lift with a 2:1 margin. For high-temperature environments up to 150 C, specify the Viton H seal option instead of the standard TPU.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X160S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 5734 N force, ensuring perfectly balanced material removal on both sides of a workpiece.
Anti-Rotation Indexing Gate
Uses the dual-rod construction to guide a heavy sliding gate without twisting or binding, maintaining precise alignment over thousands of cycles.
Dual-End Assembly Press
Forms a part on the front stroke while the rear rod extension triggers a CMSG sensor cam, synchronizing the downstream feed conveyor without extra hardware.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X160S the Right Cylinder?
Choose this 125 mm bore when your fixture requires 5734 N both ways at 0.5 MPa; step up to the 160 mm bore if you need 9425 N, or drop to smaller ISO 15552 units for lighter duties. The double-rod architecture is ideal for anti-rotation guidance, mounting twin tools, or tracking a sensor cam out the back. Available mountings include FA, LB, TC, FTC, TCM1, and TCM2. The -S magnet enables position sensing. Because the 160 mm stroke is relatively short, side-load stress is minimal, but always guide the rod end on longer travels. Remember that a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need strict load holding.
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 SGCD125X160S FAQ
Because it is a double-rod cylinder, force is equal both ways using the pull-side area. It generates 5734 N at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical maximum of 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and it features a G1/2 air port.
No, a standard double-rod cylinder will drift if air pressure is lost or the valve is centered. The adjustable 40 mm air cushions only decelerate the piston near the end of stroke; they do not act as a brake. To suspend a load safely, you must install an external rod lock or a pilot-operated check valve.
