Airtac SGCD Dual Rod Cylinder SGCD125X100
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X100 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGCD125X100
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. It yields a safe working load of roughly 3440 N, which translates to lifting about 292 kg vertically with a 2:1 safety margin. The G1/2 port feeds the 125 mm bore, operating at speeds of 30-500 mm/s.
Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the symmetric load path prevents rod twisting under offset forces. This non-magnet SKU cannot host position sensors; adding the -S variant enables CMSG, DMSG, or EMSG switches. Note that Viton H seals can raise the operating ceiling to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X100 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from a single piston, ensuring perfectly synchronized part handoff between conveyor stations.
Balanced Lift Stage
Lifts roughly 292 kg of vertical payload using the equal pull-side area, preventing the asymmetric drift common in single-rod lifts.
Anti-Rotation Press
Applies 5734 N of clamping force without rod twist, keeping precision stamping dies perfectly aligned during heavy-duty forming operations.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X100 the Right Cylinder?
Sizing the 125 mm bore places you at the lower edge of this large-frame family, offering 5734 N each way, whereas stepping up to the 160 mm bore provides 9425 N. Choose this double-rod architecture when your mechanism demands anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this 100 mm stroke is relatively short, side-load guide concerns are minimal, but any future build exceeding 500 mm stroke requires external load bearings to prevent rod 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 SGCD125X100 FAQ
The double-rod design yields equal force both ways: 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa. It operates at speeds of 30-500 mm/s.
This non-magnet SKU cannot host CMSG or DMSG sensors; you must specify the -S variant for position detection. Furthermore, a plain cylinder drifts on air loss because the adjustable 40 mm cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for secure load holding.
