Airtac SGCD Dual Rod Cylinder SGCD125X160
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X160 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 SGCD125X160
Delivering 5734 N of thrust in both directions at 0.5 MPa, the AirTAC SGCD125X160 is a genuine ISO 15552 tie-rod cylinder built for symmetric actuation. Because a rod exits both covers, the pressure area stays identical each way, yielding equal push and pull force. This twin-rod geometry prevents piston rotation and provides a stable path for mounting a sensor cam or driving two tools at once. The four steel tie rods clamp the aluminum barrel securely, and the G1/2 port handles the 125 mm bore airflow.
With a 5734 N output, this unit safely handles about 3440 N of real work, which translates to lifting roughly 292 kg vertically with a 2:1 safety margin. It runs at 30-500 mm/s and uses adjustable air cushions at both ends to decelerate the load smoothly. Note that this plain SKU lacks a magnet and cannot take CMSG/DMSG/EMSG switches; you would need the -S variant for position sensing.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X160 Is Used
Twin-Spindle Drilling
Drives two opposing machining heads simultaneously with equal force, using the extended rod on both ends to maintain perfectly synchronized cutting feed.
Symmetric Transfer Arm
Moves a transfer carriage back and forth along a conveyor line, utilizing the balanced push and pull thrust to prevent mechanical binding during rapid direction changes.
Anti-Rotation Lift Station
Raises and lowers a heavy platen without twisting, relying on the dual-rod construction to keep the load perfectly aligned through the vertical travel.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X160 the Right Cylinder?
When sizing this double-rod unit, the 125 mm bore sits at the low edge of the large-bore SGCD family, stepping up directly to the 160 mm version which outputs 9425 N both ways at 0.5 MPa. If your application needs less force, you would drop out of the SGCD range entirely, as 125 mm is the smallest available bore. Choose the SGCD125X160 when your mechanism requires anti-rotation guidance, symmetric load distribution, or a rear rod extension for tooling. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For any stroke at or above 500 mm, you must use external guide rails to prevent side-load wear on the 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 SGCD125X160 FAQ
The force is equal in both directions due to the double-rod design. 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 plain cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. For a suspended load, you must install an external rod lock or a pilot-operated check valve.
