Airtac SGCD Dual Rod Cylinder SGCD125X700S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X700S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 700mm 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 SGCD125X700S
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 G1/2 port feeds a bore that safely handles about 3440 N of real work, which translates to lifting roughly 292 kg vertically with a 2:1 safety margin. Four steel tie rods clamp the aluminum barrel for high structural rigidity.
Because the rod passes through both covers, the unit provides inherent anti-twist guidance and allows you to mount a sensor cam or tooling on the back end. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position feedback. Note that the 700 mm stroke requires external guide support to prevent rod bending under side loads.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X700S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 5734 N force, ensuring perfectly synchronized part finishing on both faces.
Anti-Rotation Indexing Lift
Lifts and lowers 292 kg vertical loads through 700 mm without piston twist, using the dual rods to maintain strict linear alignment.
Dual-Cam Sensing Conveyor
Uses the extended rear rod to trigger CMSG electronic switches, operating a diverter gate while the front rod pushes packages.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X700S the Right Cylinder?
Sizing this double-rod unit means balancing the 5734 N equal force against the neighboring bores: the larger SGCD160 provides 9425 N, while there is no smaller standard SGCD bore. A twin-rod design is the right call when you need symmetric load paths, non-rotating precision, or simultaneous dual-tool actuation. You can mount it using FA, LB, TC, FTC, TCM1, or TCM2 brackets. The -S suffix ensures readiness for CMSG/DMSG/EMSG sensors. Because the stroke is 700 mm, external load guides are mandatory to absorb side loads and prevent rod bending.
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 SGCD125X700S FAQ
Force is equal both ways at 5734 N at 0.5 MPa and 8028 N at 0.7 MPa, with a theoretical max of 1169 kgf at 1.0 MPa. It uses a G1/2 port and an M27x2.0 rod thread.
The -S indicates a built-in magnet for CMSG/DMSG/EMSG sensors. A plain cylinder drifts without live air since the cushion only decelerates; for load holding you must add an external rod lock or pilot-operated check valve.
