Airtac SGCD Dual Rod Cylinder SGCD125X100S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X100S 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 SGCD125X100S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod design for perfectly symmetric load paths. The four steel tie rods clamp the aluminium barrel securely, while the G1/2 port handles the 30-500 mm/s speed range. A rod exits both covers on one shared piston, meaning the pressure area and output force stay identical each way.
With the built-in -S magnet, you can track position using CMSG, DMSG or EMSG switches. This 125 mm bore unit handles about 3440 N of real work safely, which translates to lifting roughly 292 kg vertically with a 2:1 margin. The standard TPU seals offer long life from -20 to +70 C, though a Viton H option extends heat resistance up to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X100S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with equal 5734 N force, keeping the cutting cycle perfectly balanced and synchronized.
Anti-Rotation Indexing
Uses the dual-rod geometry to prevent piston twist during high-speed positioning, ensuring the 100 mm stroke maintains strict linear alignment.
Symmetric Clamping Press
Clamps heavy workpieces from both ends simultaneously, utilizing the equal push and pull forces to distribute 3440 N of safe working load evenly.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X100S the Right Cylinder?
This 125 mm bore sits at the low edge of the SGCD range, offering 5734 N equal-both-ways force at 0.5 MPa. If your application requires less power, you must drop out of the double-rod family entirely, as there is no smaller SGCD bore. If you need more force, stepping up to the 160 mm bore yields 9425 N each way. Choose this double-rod configuration when you need anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path. It supports FA, LB, TC, FTC, TCM1 and TCM2 mountings. The -S suffix ensures readiness for CMSG/DMSG/EMSG sensors. Since the 100 mm stroke is under 500 mm, side-load guide requirements are minimal.
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 SGCD125X100S FAQ
Because it is a double-rod cylinder, force is equal in both directions using the rod-side area. It outputs 5734 N at 0.5 MPa and 8028 N at 0.7 MPa each way, with a theoretical max of 1169 kgf at 1.0 MPa. The bore is 125 mm, the port is G1/2, and the rod-end thread is M27x2.0.
No, a plain cylinder drifts on air loss and the adjustable air cushions only decelerate near stroke end; use an external rod lock or pilot-operated check valve for holding. The -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG position switches.
