Airtac SGCD Dual Rod Cylinder SGCD250X450S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD250X450S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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 SGCD250X450S
Delivering 23562 N of equal force in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod piston to balance heavy loads perfectly. The symmetric design prevents rotation and provides an excellent safe working load of about 14137 N, which is roughly 1201 kg of vertical lift capacity with a 2:1 safety margin. Four steel tie rods clamp the aluminum barrel securely, and the G1 air port handles high flow volumes easily.
Because this is a 250 mm bore model, TPU seals are not available; instead, it uses durable NBR packings with a Viton H option for high-temperature environments up to 150 C. The built-in -S magnet allows precise position sensing using CMSG, DMSG, or EMSG switches. You can drop this unit directly into existing ISO 15552 mounting interface fixtures without compatibility concerns.

Theoretical Output Force (Ø250mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD250X450S Is Used
Twin-Press Stamping
Drives two opposing forming tools simultaneously from a single piston, ensuring perfectly balanced impact force across wide heavy-gauge metal panels.
Symmetric Platen Lowering
Lowers heavy machinery platens without twisting, using the dual output rods to maintain strict parallel alignment during high-tonnage descent.
Dual-Lane Diverting
Pushes parallel product lanes at the exact same time and speed, using the rear rod extension to carry a mirrored sensor cam for synchronized tracking.
Is the Airtac SGCD Dual Rod Cylinder SGCD250X450S the Right Cylinder?
When sizing this double-acting cylinder, consider stepping down to the 200 mm bore if your application only requires 15079 N of equal both-ways force at 0.5 MPa, as the 250 mm bore sits at the top of the range with massive 23562 N output. Choose the double-rod configuration when you need strict anti-rotation control, twin tooling operation from a single actuator, or a symmetric load path to prevent side-loading. Available mounts include FA, LB, TC, FTC, TCM1, and TCM2. The -S magnet is essential if you require electronic or reed switch feedback. For this 450 mm stroke, ensure external guide rails support any heavy lateral loads to 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 SGCD250X450S FAQ
The push and pull force is equal both ways due to the double-rod design. It generates 23562 N at 0.5 MPa, 32986 N at 0.7 MPa, and a theoretical maximum of 4805 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa, with a 1.5 MPa proof pressure.
No, a standard double-rod cylinder will drift without live air, as the adjustable 60 mm air cushions only decelerate the piston near the end of stroke. To maintain a vertical load position safely, you must install an external rod lock or a pilot-operated check valve.
