Airtac SGCD Dual Rod Cylinder SGCD125X175S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X175S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 175mm 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 SGCD125X175S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to equalize output force. The G1/2 port feeds a robust four-steel-tie-rod aluminium barrel. Because the rod passes through both covers, the pressure area stays identical each way, yielding 8028 N at 0.7 MPa.
This symmetric load path resists torsional twist and provides a rear shaft for secondary tooling or cam tracking. The built-in -S magnet enables CMSG, DMSG, or EMSG position switches. Factoring a 60 percent safety margin, expect about 3440 N of reliable work, which translates to lifting roughly 292 kg vertically.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X175S Is Used
Twin-Tool Transfer
Drives two opposing forming tools simultaneously from one piston, utilizing the equal force on both rod ends to maintain perfectly synchronized press cycles.
Anti-Rotation Indexer
Moves a precision gauging head back and forth without rotational drift, relying on the dual shafts to keep the measurement plane perfectly parallel.
Symmetric Lift Station
Balances a 292 kg vertical lift payload using the equal push and pull thrust, preventing sagging on the return stroke thanks to the matched rod areas.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X175S the Right Cylinder?
Size this 125 mm bore against its neighbours: step down to the 160 mm unit for 9425 N, or keep this model for its 5734 N equal-both-ways output. A double-rod layout is the right call when you need anti-rotation stability, twin tooling stations, or a back-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix confirms your magnet is present for electronic sensing. For this 175 mm stroke, ensure external guide rails carry any lateral load 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 SGCD125X175S FAQ
Force is equal both ways due to the double-rod design: 5734 N at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical max of 1169 kgf at 1.0 MPa. It uses a G1/2 port and an M27x2.0 rod thread.
No. The adjustable 40 mm air cushions only decelerate the piston near stroke end; they do not lock the load. If air is lost, the rod drifts. Use an external rod lock or pilot-operated check valve for secure load holding.
