Airtac SGCD Dual Rod Cylinder SGCD125X75S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X75S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 75mm 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 SGCD125X75S
Delivering exactly 5734 N of thrust and pull at 0.5 MPa, this double-acting AirTAC SGCD125X75S cylinder uses a through-rod piston to guarantee identical force in both directions. The twin-rod layout creates a symmetric load path that resists torsional twist, making it ideal for guiding heavy platens or driving two tools at once. It features a G1/2 port and a built-in piston magnet for CMSG/DMSG/EMSG switches.
Built on a genuine ISO 15552 tie-rod frame, four steel rods clamp the aluminum barrel to deliver rigid, high-pressure performance up to 1.0 MPa. The 5734 N output translates to a safe working load of about 3440 N, which can vertically lift roughly 292 kg with a 2:1 safety margin. Standard TPU seals handle temperatures from -20 to +70 C, while adjustable 40 mm air cushions at both ends absorb end-of-stroke impact.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X75S Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously with equal 5734 N force, using the through-rod design to maintain strict parallelism without rotational drift.
Symmetric Divert Gate
Uses both rod ends to push and pull a diverting flap from opposite sides, ensuring the load path remains balanced and preventing guide bushing wear.
Vertical Lift Platen
Lifts heavy palletized loads straight up, relying on the equal pull force and anti-twist geometry to keep the platen level during rapid 30-500 mm/s transit.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X75S the Right Cylinder?
This 125 mm bore sits at the lower edge of the SGCD large-bore family, offering 5734 N each way at 0.5 MPa. If your application needs less force, step down is not available within this double-rod series, so consider a smaller ISO 15552 profile. If you require more power, the 160 mm bore provides 9425 N both ways. Choose the double-rod configuration when you need anti-rotation stability, twin tooling drives, or a back-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix indicates the internal magnet is present for CMSG/DMSG/EMSG sensors. For any stroke over 500 mm, always use external guide rails to prevent side-load 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 SGCD125X75S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum force is 1169 kgf at 1.0 MPa. It uses a G1/2 port.
The -S means a piston magnet is installed, allowing direct mounting of CMSG, DMSG, or EMSG reed or electronic switches. Note that a plain cylinder does not hold load on air loss; the cushions only decelerate. Use an external rod lock or pilot-operated check valve for held loads.
