Airtac SGCD Dual Rod Cylinder SGCD250X175S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X175S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 175mm stroke, G1 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 SGCD250X175S
Delivering 23562 N of thrust in both directions at 0.5 MPa, the AirTAC SGCD250X175S is a genuine ISO 15552 tie-rod cylinder with a piston rod exiting both covers. Because the pressure area is identical on each face, push and pull forces remain perfectly equal. The four steel tie rods clamp the aluminum barrel securely, while the G1 air port handles the high volume needed for this large 250 mm bore. An integrated magnet allows for precise position detection.
This double-rod configuration provides a symmetric load path that resists torsional twisting, making it ideal for guiding heavy platens or driving twin tool stations simultaneously. It yields a safe working load of roughly 14137 N, which translates to lifting about 1201 kg vertically with a 2:1 safety margin. Note that standard NBR seals are used here, as TPU is not available on this bore size, though a Viton H option extends operating temperatures up to 150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X175S Is Used
Twin-Tool Stamping
Drives two forming tools simultaneously from a single piston, ensuring perfectly synchronized press strokes using both rod ends.
Symmetric Platen Lift
Lifts heavy machining platens without torsional deflection, as the dual rods create a balanced load path that resists twisting.
Dual-End Diverting
Actuates sorting flaps on both sides of a high-capacity transfer line, using the through-rod to push opposing diverters at once.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X175S the Right Cylinder?
Sitting at the top of the SGCD range, this 250 mm bore provides maximum thrust, stepping up significantly from the 200 mm bore which offers 15079 N at 0.5 MPa. Choose a double-rod design when your mechanism requires strict anti-rotation control, symmetric load distribution, or a rear rod extension to mount a sensor cam. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix indicates the piston is equipped for CMSG, DMSG, or EMSG switches. Even with a moderate 175 mm stroke, always support side loads with external guide rails to prevent premature seal wear.
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 SGCD250X175S FAQ
Because it is a double-rod cylinder, force is equal in both directions using the pull-side area. It generates 23562 N at 0.5 MPa and 32986 N at 0.7 MPa, with a theoretical maximum of 4805 kgf at 1.0 MPa. The bore is 250 mm, the rod is 50 mm with an M42x2.0 thread, and the air port is G1.
A plain cylinder cannot hold a load without live air; the 60 mm adjustable air cushions only decelerate the piston near stroke end. For suspended loads, install an external rod lock or pilot-operated check valve. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG position switches.
