Airtac SGCD Dual Rod Cylinder SGCD125X600S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X600S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 600mm 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 SGCD125X600S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore tie-rod cylinder uses a twin-rod piston to ensure perfectly symmetric load paths. The four steel tie rods clamp the aluminum barrel to the covers, giving genuine ISO 15552 mounting-interface interchangeability for your existing fixtures. It breathes through a G1/2 port and runs at 30-500 mm/s.
Because the rod passes through both covers, the output force is equal both ways, making it good for about 3440 N of real work, roughly 292 kg lifted vertically. The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG position sensing. Note that standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 0-150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X600S Is Used
Twin-Tool Drive
Drives two opposing forming tools simultaneously from both rod ends, ensuring perfectly synchronized press cycles without mechanical linkages.
Balanced Lift Station
Lifts heavy platens vertically with equal force both ways, using the symmetric load path to prevent guide bushing wear and platform tilting.
Anti-Rotation Indexer
Moves a machining fixture back and forth while the dual rods prevent torsional deflection, maintaining high repeatability over the 600 mm travel.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X600S the Right Cylinder?
This 125 mm bore sits at the lower edge of the SGCD range, so if your application needs less thrust, step down to a smaller profile, but if you need more power, the 160 mm bore provides 9425 N both ways at 0.5 MPa. A double-rod design is the right call when you need anti-rotation guidance, twin tooling driven from both ends, or a rear sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a 600 mm stroke, you must use external guides to prevent rod bending and manage side loads. The -S magnet enables electronic or reed switch sensing.

- ✓ 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 SGCD125X600S FAQ
The double-rod design yields equal force in both directions: 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and it uses a G1/2 port.
No, a standard cylinder drifts without live air, as the adjustable 40 mm air cushions only decelerate the piston near stroke end. For vertical load holding, install an external rod lock or a pilot-operated check valve.
