Airtac SGCD Dual Rod Cylinder SGCD200X125S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X125S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 125mm stroke, G3/4 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 SGCD200X125S
Delivering 15079 N of thrust in both directions at 0.5 MPa, this large-bore double-rod cylinder eliminates the area differential found in single-rod units. The piston rod passes through both covers, yielding perfectly symmetric output forces whether extending or retracting. It features a G3/4 port and a robust four steel tie-rod construction that clamps the aluminum barrel securely to the end covers.
Because the -S suffix denotes a built-in piston magnet, this model is fully compatible with CMSG, DMSG, and EMSG electronic or reed switches for precise end-position detection. The genuine ISO 15552 mounting interface guarantees dimensional interchangeability for your large-bore fixtures. With 15079 N available each way, you get a safe working load of roughly 9047 N, which is ideal for lifting about 769 kg vertically with a 2:1 safety margin. Standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this range up to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD200X125S Is Used
Twin-Tool Machining Station
Drives opposing machining heads simultaneously from a single symmetric piston, ensuring perfectly timed cutting cycles on both sides of a heavy workpiece.
Balanced Lift Platform
Lifts heavy industrial platforms evenly using the rod out each end, preventing torsional twist and maintaining precise vertical alignment under load.
Dual-End Transfer Gate
Actuates a transfer gate by pushing from the back end while pulling from the front, keeping the load path perfectly centered for high-speed conveying.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X125S the Right Cylinder?
This 200 mm bore sits between the 160 mm option, which provides 9425 N both ways at 0.5 MPa, and the 250 mm version, which delivers 23562 N. Choose the double-rod configuration when your mechanism requires anti-rotation guidance, needs to drive two separate tools simultaneously from one piston, or demands a symmetric load path. The -S magnet allows seamless integration with CMSG, DMSG, or EMSG sensors. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For any stroke at or above 500 mm, you must use external guide rails to prevent side-load damage to the rod seals.
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 SGCD200X125S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It outputs 15079 N at 0.5 MPa and 21110 N at 0.7 MPa. The theoretical maximum force is 3075 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a 1.5 MPa proof pressure.
No, a standard cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near the stroke end. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
