Airtac SGCD Dual Rod Cylinder SGCD125X300S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X300S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 300mm 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 SGCD125X300S
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 balance the load path entirely. The twin rods exit both covers, providing anti-rotation guidance and allowing you to mount a sensor cam or secondary tool on the back end. It yields a safe working load of roughly 3440 N, which is enough to vertically lift about 292 kg with a 2:1 safety margin. Four steel tie rods clamp the aluminum barrel, and the G1/2 port feeds a double-acting chamber operating at 30-500 mm/s.
Because the rod occupies both faces, the pull-side area dictates the output, making the push and pull forces identical. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 150 C. The built-in -S magnet enables CMSG, DMSG, or EMSG switch tracking. Note that the adjustable 40 mm cushions only decelerate the piston near the ends; an external rod lock or pilot-operated check valve is required to hold a suspended load.

Where the Airtac SGCD Dual Rod Cylinder SGCD125X300S Is Used
Twin-Tool Indexing
Drives two opposing tools simultaneously from one piston, utilizing the equal force on both rods for perfectly synchronized forming or clamping operations.
Balanced Lift Station
Lifts roughly 292 kg of vertical load with a 2:1 safety margin, using the symmetric double-rod design to prevent platform twisting during elevation.
Anti-Rotation Gate
Actuates a heavy guard gate where the twin rods resist torsional side loads, maintaining alignment without requiring external linear bearings.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X300S the Right Cylinder?
This 125 mm bore sits at the lower edge of the SGCD range, offering 5734 N each way at 0.5 MPa. If your application needs less force, you must step outside the SGCD family, as 125 mm is the smallest available size. If you need more power, the 160 mm bore provides 9425 N both ways. Choose the double-rod configuration when your mechanism requires anti-rotation stability, symmetric load distribution, or a rear-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix confirms the piston magnet is present for CMSG/DMSG/EMSG switches. For this 300 mm stroke, ensure external guide rails are used to absorb any lateral side loads and prevent 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 SGCD125X300S FAQ
The force is equal in both directions due to the double-rod design. It provides 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. The air port size is G1/2.
The S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG electronic switches. The cylinder cannot hold a load without live air; the air cushions only decelerate movement near the stroke ends. Use an external rod lock or pilot-operated check valve for secure load holding.
