Airtac SGC Standard Cylinder SGC125X220
The AirTAC Airtac SGC Standard Cylinder SGC125X220 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 220mm 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 SGC Standard Cylinder SGC125X220
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore unit brings genuine ISO 15552 mounting-interface interchangeability to large-bore pneumatic setups. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while a two-way piston seal maintains an internal oil reservoir to maximize service life. The G1/2 port and M27x2.0 rod thread handle the required air volume for a 220 mm stroke.
For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. The standard TPU seals operate from -20 to +70 C, with Viton H available for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC125X220 Is Used
Press Ejection
Ejects formed metal stampings from a 150-ton press bed, utilizing the 6136 N push force to reliably clear heavy parts within a 220 mm stroke.
Pallet Stopper
Acts as a heavy-duty stopping gate on a chain conveyor, absorbing the impact of loaded pallets using the rigid four-tie-rod construction.
Flap Folding
Folds heavy corrugated cardboard flaps on large industrial cartons, applying consistent pressure across the 220 mm travel distance.
Is the Airtac SGC Standard Cylinder SGC125X220 the Right Cylinder?
When sizing this 125 mm bore actuator against the SGC family, dropping down is not an option as it is the smallest available size. Stepping up to the 160 mm bore significantly increases capability to 10053 N push at 0.5 MPa if your application outgrows the 6136 N rating here. Keep in mind that a standard cylinder drifts when air is lost or a valve centers; the adjustable 40 mm air cushions only decelerate the piston near stroke ends rather than locking the load. For secure holding, integrate an external rod lock or pilot-operated check valve. Since this 220 mm stroke is relatively moderate, severe side-load bending is less critical than on longer strokes, but proper guide alignment remains essential. To add sensing capabilities, you must select the -S magnet variant.
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 SGC Standard Cylinder SGC125X220 FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, increasing to 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S variant to enable CMSG, DMSG, or EMSG magnetic switches. However, all SGC models share the standardized ISO 15552 mounting interface, allowing you to drop this tie-rod cylinder into existing large-bore fixtures.
