About the Airtac SGC Standard Cylinder SGC125X75S
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore tie-rod cylinder is built for rigorous large-bore automation. The four steel tie rods clamp the aluminum barrel to the covers, providing the structural rigidity needed to handle high thrust without flexing. A heterogeneous two-way piston seal maintains an internal oil reservoir to ensure long-term lubrication and seal life. Because it adheres to the ISO 15552 mounting interface, it drops directly into existing large-bore fixture footprints without requiring custom brackets.
Equipped with a 75 mm stroke and a G1/2 air port, this specific SKU includes the -S magnet option, enabling seamless integration with CMSG, DMSG, or EMSG electronic switches for precise end-of-stroke detection. 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 adjustable 40 mm air cushions at both ends absorb kinetic energy near the stroke limits, protecting the mechanism from impact.

Where the Airtac SGC Standard Cylinder SGC125X75S Is Used
Press Fit Assembly
Drives small bushings and bearings into automotive housings, utilizing the 6136 N push force to ensure complete seating without damaging delicate components.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop in high-throughput conveyor lines, extending 75 mm to halt loaded pallets weighing up to 313 kg safely.
Carton Flap Folder
Executes rapid mid-stroke folding motions on large industrial packaging lines, relying on the -S magnet to trigger the next machine cycle via DMSG sensors.
Is the Airtac SGC Standard Cylinder SGC125X75S the Right Cylinder?
When sizing this 125 mm bore unit, verify your actual load requirements against the 6136 N push rating at 0.5 MPa. If your application demands less force, stepping down is not possible within the SGC series as this is the smallest available bore; you would need to look at smaller standard cylinders. If you need substantially more power, the next size up is the 160 mm bore, which provides 10053 N of push force at 0.5 MPa. For this 75 mm stroke, side-load stress on the 32 mm rod is minimal, but always ensure proper alignment to prevent premature seal wear.
Because this is a double-acting pneumatic actuator, it will not hold a load in place if air pressure is lost or the control valve is centered—the piston will drift. The end-of-stroke cushions only decelerate the piston and do not act as a mechanical brake. If your setup requires strict position holding, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SGC125X75S 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.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the barrel for reed or electronic sensing. Additionally, its ISO 15552 mounting interface means it is dimensionally interchangeable with other standard large-bore cylinders, simplifying spare parts inventory and fixture design.
