Airtac SGCD Dual Rod Cylinder SGCD125X1000S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X1000S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGCD125X1000S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod architecture to equalize output force. The design passes a Ø32 mm piston rod through both covers, yielding a symmetric load path that resists torsional twist while allowing twin tooling or a rear sensor cam to run simultaneously. It handles a safe working load of roughly 3440 N, which translates to lifting about 292 kg vertically with a 2:1 safety margin. Four steel tie rods clamp the aluminum barrel, and the G1/2 port feeds a two-way piston seal rated for 0.15 to 1.0 MPa.
Because the -S suffix denotes a built-in piston magnet, this SKU directly supports CMSG, DMSG, and EMSG electronic switches for end-of-stroke confirmation. The standard TPU seals operate from -20 to +70 C, though a Viton H option extends this to 0-150 C for thermal extremes. Adjustable 40 mm air cushions at both ends decelerate the 1000 mm travel smoothly. Note that a plain cylinder drifts on air loss; the cushions only slow the piston near stroke end, so fit an external rod lock or pilot-operated check valve for held loads.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X1000S Is Used
Dual-Station Transfer
Uses both rod ends to push and retract identical workpieces simultaneously on parallel conveyor lines, keeping cycle times perfectly synchronized.
Anti-Twist Pressing
Employs the symmetric twin-rod load path to press bearings without piston rotation, ensuring perpendicular insertion over long 1000 mm travels.
Vertical Lift Gate
Lifts a 292 kg safety gate using the equal pull force, relying on external guides to manage the lengthy stroke and prevent rod deflection.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X1000S the Right Cylinder?
Sizing this 125 mm bore against its neighbors helps verify your choice. If 5734 N each way at 0.5 MPa is excessive, step down to the 160 mm bore (9425 N) or evaluate smaller SGC single-rod options. If you need more power, step up to the 160 mm bore or the 200 mm bore (15079 N). The 125 mm sits at the low edge of the SGCD range. Choose a double-rod configuration when your mechanism demands anti-rotation stability, symmetric load distribution, or a rear extension to drive a secondary tool. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets, all conforming to ISO 15552 mounting-interface dimensions for fixture interchangeability. The -S magnet enables position sensing. Because the 1000 mm stroke is substantial, always provide external guide rails to prevent rod bending under side loads.
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 SGCD125X1000S FAQ
The double-rod design yields equal force both ways: 5734 N at 0.5 MPa, 8028 N at 0.7 MPa, and a theoretical maximum of 1169 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a 1.5 MPa proof pressure. The G1/2 port supplies air to the chambers.
No, a plain cylinder drifts if air fails; the 40 mm cushions only decelerate motion at stroke ends. Use an external rod lock or pilot-operated check valve to hold loads. The -S suffix means it has a piston magnet ready for CMSG, DMSG, or EMSG reed and electronic switches.
