Airtac SGCD Dual Rod Cylinder SGCD250X175
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X175 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 SGCD250X175
Delivering 23562 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 design outputs a rod from each end, providing symmetric load paths and excellent anti-rotation guidance for heavy industrial tooling. Four steel tie rods clamp the aluminum barrel securely to the covers.
It features a G1 air port, a 50 mm piston rod, and 60 mm adjustable air cushions at both ends. Because this is a 250 mm bore, TPU seals are unavailable and NBR gaskets are standard, though a Viton H option extends operating temperatures to 0-150 C. With a safe working load around 14137 N, it can reliably lift approximately 1201 kg vertically with a 2:1 safety margin.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |
| Max (@1.0 MPa) | 5006 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac SGCD Dual Rod Cylinder SGCD250X175 Is Used
Twin-Spindle Press
Drives two opposing forming tools simultaneously using both rod ends, ensuring perfectly balanced high-tonnage pressing without rotational drift.
Heavy Platen Lowering
Lowers heavy machinery platens with equal push and pull force, using the symmetric load path to prevent binding during vertical descent.
Dual-Side Divertor
Actuates diverters on both sides of a wide conveyor belt simultaneously from a single centralized ISO 15552 mounting fixture.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X175 the Right Cylinder?
As the largest standard bore, the 250 mm size sits at the high edge of the range, offering significantly more force than the 200 mm bore which provides 15079 N at 0.5 MPa. Choose this double-rod configuration when your application demands anti-rotation stability, twin-tool driving from one piston, or a symmetric load path. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Note that this specific SKU lacks the -S magnet and cannot accept CMSG/DMSG/EMSG sensors. For any stroke over 500 mm, external guide rails should be used to prevent side-load wear on 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 SGCD250X175 FAQ
The double-rod design yields equal force both ways: 23562 N at 0.5 MPa and 32986 N at 0.7 MPa. The theoretical maximum is 4805 kgf at 1.0 MPa, which is the absolute pressure limit.
No, a plain cylinder drifts on air loss and the cushions only decelerate near stroke end; use an external rod lock or pilot-operated check valve to hold loads. Also, this SKU lacks the -S magnet and cannot mount CMSG/DMSG/EMSG sensors.
