About the Airtac SGC Standard Cylinder SGC125X75STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder is built on a genuine ISO 15552 tie-rod framework. Four steel rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The standardized ISO 15552 mounting interface ensures it drops directly into existing large-bore fixtures.
Equipped with a built-in piston magnet (-S), the unit supports CMSG, DMSG, and EMSG switches for position sensing. It features a 32 mm rod, a G1/2 port, and a 75 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.

Where the Airtac SGC Standard Cylinder SGC125X75STC Is Used
Press Fit Assembly
Drives bearings into heavy housings on automotive production lines, utilizing the 6136 N push force to seat components reliably.
Pallet Stopper Gate
Acts as a robust pneumatic stop in high-speed conveyor systems, raising a 75 mm barrier to halt loaded pallets.
Carton Flap Folder
Folds heavy corrugated cardboard flaps on large case erectors, using the TC trunnion mount to accommodate pivot geometry.
Is the Airtac SGC Standard Cylinder SGC125X75STC the Right Cylinder?
This 125 mm bore provides 6136 N push and 5734 N pull at 0.5 MPa. If your application requires less force, there is no smaller bore in the SGC family; stepping up to the 160 mm bore yields 10053 N of push force. The included TC trunnion mount utilizes the ISO 15552 interface for precise pivot actuation. Because this model includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG sensors.
Remember that a standard double-acting cylinder will drift and lose its position if air pressure drops or the valve is centered. The adjustable air cushions only decelerate the piston near the end of stroke; they do not act as a brake. To safely hold a load vertically, integrate an external rod lock or a pilot-operated check valve into your 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 SGC125X75STC FAQ
This 125 mm bore cylinder features a G1/2 air port and generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N and the pull force is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, the air cushions only decelerate the piston near the stroke ends and do not function as a brake; the piston will drift if air is lost, requiring an external rod lock for holding. Because this model includes the -S magnet, it fully supports CMSG, DMSG, and EMSG position switches.
