Airtac SGC Standard Cylinder SGC125X700STC
The AirTAC Airtac SGC Standard Cylinder SGC125X700STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 700mm 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 SGC125X700STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles large-bore automation with ease. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG position switches for end-of-stroke detection. Fluid porting is G1/2, and the standard TPU seal handles temperatures from -20 to +70 C, with a Viton H option available for 0-150 C environments. Because this unit carries a 700 mm stroke, external guide rails should support the rod end to prevent excessive side loading and rod bending during extension.

Where the Airtac SGC Standard Cylinder SGC125X700STC Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets sideways onto secondary conveyor lines using its 6136 N thrust capacity and 700 mm extension.
Warehouse Lift Gate
Raises material handling gates, safely lifting components up to 313 kg vertically when applying a 2:1 safety margin at 0.5 MPa.
Automated Press Ejection
Ejects formed metal parts from large stamping presses, utilizing the TC trunnion mount to handle pivoting articulation.
Is the Airtac SGC Standard Cylinder SGC125X700STC the Right Cylinder?
When sizing this 125 mm bore against its neighbors, step down to the smaller SGC series if your load requires less than 6136 N at 0.5 MPa, or step up to the 160 mm bore (which provides 10053 N at 0.5 MPa) if you need substantially more thrust. The included TC trunnion mount utilizes the standardized ISO 15552 mounting interface, ensuring it drops directly into existing large-bore fixtures and accessory brackets.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near stroke ends and do not function as a locking brake. To suspend a vertical load safely, install 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 SGC125X700STC FAQ
The G1/2 ported 125 mm bore yields 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
It uses a TC trunnion mount dimensionally interchangeable per the ISO 15552 mounting interface. The included -S magnet allows direct fitting of CMSG, DMSG, or EMSG switches for position sensing.
