About the Airtac SGC Standard Cylinder SGC125X1200SN
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious power to long-reach tasks. The SGC125X1200SN utilizes a genuine ISO 15552 mounting interface, dropping directly into existing large-bore fixtures without hassle. Four steel tie rods clamp the aluminum barrel to the front and rear covers, providing the high rigidity needed to handle large-bore thrust, while a two-way piston seal maintains an internal oil reservoir for extended operational life.
Because this specific SKU includes the -S magnet, it is fully primed for CMSG, DMSG, or EMSG position switches. It also carries the -N NBR seal designation. 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. The unit features a G1/2 port and a 1200 mm stroke.

Where the Airtac SGC Standard Cylinder SGC125X1200SN Is Used
Automated Pallet Transfer
Pushes heavy loaded pallets across long conveyor gaps, utilizing the 1200 mm stroke to bridge distant workstations efficiently.
Vertical Material Lift
Raises components weighing up to 313 kg in high-bay storage systems, relying on the 6136 N thrust at 0.5 MPa for steady elevation.
Large Press Ejection
Ejects finished stamped parts from deep press beds, where the NBR seals handle varied shop temperatures and the long stroke clears the tooling.
Is the Airtac SGC Standard Cylinder SGC125X1200SN the Right Cylinder?
When sizing this 125 mm bore option, note that it sits at the lower end of the SGC large-bore family, meaning there is no smaller standard SGC bore available; if you need less force, you must look outside the SGC series. If your application demands more thrust, stepping up to the 160 mm bore yields 10053 N of push force at 0.5 MPa. Because this model features a 1200 mm stroke, external guide rails are highly recommended to prevent rod bending and absorb side loads during long extensions. Additionally, a plain cylinder drifts when air is lost or a valve is centered; the end cushions only decelerate the piston near stroke end and do not act as a brake. For suspended or vertical loads, integrate an external rod lock or a pilot-operated check valve.
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 SGC125X1200SN FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, and 8590 N push / 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches along the barrel. Furthermore, its ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures and accessories.
