Airtac SGCD Dual Rod Cylinder SGCD125X200
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X200 is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCD125X200
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. The symmetrical load path prevents rotation and provides stable anti-twist guidance. At 0.5 MPa it is good for about 3440 N of real work, roughly 292 kg lifted vertically. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. A G1/2 port supplies the air.
This 125 mm bore unit features a 32 mm piston rod and an M27x2.0 rod-end thread. Adjustable 40 mm air cushions at both ends decelerate the piston smoothly. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option instead of the standard TPU.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X200 Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously using the rods protruding from both covers, ensuring perfectly synchronized cutting cycles.
Symmetric Transfer Pusher
Pushes a workpiece forward while moving an empty pallet backward at the same speed, utilizing the equal force and anti-twist properties.
Balanced Vertical Lift
Lifts roughly 292 kg of payload vertically with a 2:1 safety margin, relying on the symmetric load path to prevent piston rod binding.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X200 the Right Cylinder?
Choose this 125 mm bore when you need 5734 N of equal both-ways force at 0.5 MPa. If your application requires less thrust, the smaller 160 mm bore offers 9425 N; if you need more, the 250 mm bore provides 23562 N. A double-rod design is the right call for anti-rotation tasks, driving twin tooling from both ends, or mounting a sensor cam on the back rod. It supports FA, LB, TC, FTC, TCM1, and TCM2 mounts. To add magnetic position sensing, you must select the -S variant. Since the 200 mm stroke is under 500 mm, external guide rails are less critical, but always verify side-load limits.
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 SGCD125X200 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It delivers 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 air port.
No, this specific SKU does not have the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG sensors. You must order the -S variant to enable magnetic position sensing.
