Airtac SGCD Dual Rod Cylinder SGCD125X175
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X175 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 SGCD125X175
Delivering exactly 5734 N of thrust and pull at 0.5 MPa, the SGCD125X175 uses a twin-rod piston to keep output force identical in both directions. This AirTAC large-bore ISO 15552 tie-rod cylinder features a G1/2 port, a 32 mm rod with an M27x2.0 thread, and 40 mm adjustable air cushions at each end. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity.
Because the rod passes through both covers, it provides a symmetric load path that resists torsional twist and can drive tooling from the back end. This equal-both-ways force is good for about 3440 N of real work, roughly 292 kg lifted vertically with a 2:1 margin. The default TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X175 Is Used
Twin-Tool Indexing
Drives two opposing forming tools simultaneously from both rod ends, keeping cycle timing perfectly synchronized without adding external linkages.
Anti-Rotation Press
Uses the symmetric double-rod load path to prevent piston twist during high-force pressing operations, ensuring the ram stays perfectly aligned.
Balanced Vertical Lift
Lifts roughly 292 kg of payload with a 2:1 safety margin, using equal pull and push forces to smoothly raise and lower heavy platens.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X175 the Right Cylinder?
Size this 125 mm bore against the 160 mm option if you need more power; the 160 delivers 9425 N each way at 0.5 MPa, whereas the 125 provides 5734 N. Choose the double-rod configuration when your mechanism requires anti-rotation guidance, twin tooling stations, or a symmetric load path. Mounting hardware includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 styles. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. For any stroke at or 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 SGCD125X175 FAQ
Because it is a double-rod cylinder, force is equal in both directions. It outputs 5734 N at 0.5 MPa and 8028 N at 0.7 MPa each way. The theoretical maximum is 1169 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod, and operates at 30-500 mm/s.
No, this SKU lacks the -S magnet and cannot take CMSG, DMSG, or EMSG sensors. Furthermore, a plain cylinder drifts on air loss; the air cushions only decelerate near stroke end. To hold a load vertically, install an external rod lock or a pilot-operated check valve.
