Airtac SGCD Dual Rod Cylinder SGCD125X125S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD125X125S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGCD125X125S
Delivering 5734 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses a twin-rod architecture to provide perfectly symmetric output. The double-rod layout means the pressure area is identical on both piston faces, making it ideal for anti-rotation guidance or driving two tools simultaneously from one unit. Four steel tie rods clamp the aluminum barrel securely to the covers, ensuring structural rigidity under high dynamic loads.
At 0.5 MPa it handles a safe working load of about 3440 N, which translates to lifting roughly 292 kg vertically with a 2:1 safety margin. This SGCD125X125S variant includes a built-in piston magnet for position sensing and uses a G1/2 air port. The standard TPU seals operate from -20 to +70 C, though a Viton H option extends this range up to 150 C for hot environments.

Theoretical Output Force (Ø125mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |

Where the Airtac SGCD Dual Rod Cylinder SGCD125X125S Is Used
Twin-Spindle Drilling
Drives two opposing machining heads simultaneously with equal 5734 N force, keeping the thrust balanced and preventing spindle deflection during deep-hole drilling.
Symmetric Lift Platform
Lifts roughly 292 kg of vertical payload using both rod ends to maintain parallel motion without twisting, eliminating the need for extra linear guides.
Dual-End Transfer Pusher
Pushes a workpiece forward on one belt while retracting a return actuator on a parallel belt, using the equal bidirectional force to synchronize two material flows.
Is the Airtac SGCD Dual Rod Cylinder SGCD125X125S the Right Cylinder?
Sizing this actuator requires comparing the equal-both-ways force against neighboring bores: the 125 mm bore yields 5734 N at 0.5 MPa, stepping up to the 160 mm bore provides 9425 N, while dropping below this range to smaller SGC series units lowers the output. Choose the 125 mm double-rod design when your mechanism demands anti-rotation stability, a symmetric load path, or a rear-end sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix indicates the piston magnet is present, enabling CMSG, DMSG, or EMSG switch integration. Since the 125 mm stroke is under 500 mm, external guide rails are less critical, but always support side loads to prevent seal wear. Note that a standard cylinder cannot hold a load without live air; use an external rod lock or pilot-operated check valve for fail-safe holding.
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 SGCD125X125S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 5734 N at 0.5 MPa and 8028 N at 0.7 MPa. The theoretical maximum is 1169 kgf at 1.0 MPa. This 125 mm bore unit features a G1/2 air port and a 32 mm piston rod.
The S suffix means the cylinder has a built-in piston magnet. It is fully compatible with AirTAC CMSG, DMSG, and EMSG reed or electronic switches. A non-S SKU lacks this magnet and cannot accept sensors.
