Airtac SGC Standard Cylinder SGC125X1000STC
The AirTAC Airtac SGC Standard Cylinder SGC125X1000STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGC125X1000STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles long 1000 mm strokes with a 125 mm bore. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while a two-way piston seal maintains an internal oil reservoir for extended lifespan. The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG position switches.
Because of its generous travel length, plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. Air enters via the G1/2 port, and the M27x2.0 rod end threads into your tooling. The adjustable 40 mm air cushions at both ends absorb kinetic energy, but a side-load guide is essential over this 1-meter extension to prevent rod bending.

Where the Airtac SGC Standard Cylinder SGC125X1000STC Is Used
Pallet Transfer Line
Pushes heavy loaded pallets 1 meter across a manufacturing cell, relying on the 6136 N thrust and 40 mm cushions to stop smoothly without slamming.
Vertical Material Lift
Raises 300 kg components between elevator tiers, using the TC trunnion to pivot safely while external guides absorb lateral payload weight.
Press Ejection System
Ejects finished metal parts from a hydraulic press bed over a long 1000 mm reach, utilizing the CMSG sensors to confirm full ejection.
Is the Airtac SGC Standard Cylinder SGC125X1000STC the Right Cylinder?
This 125 mm bore sits at the lower end of the SGC large-bore family. If 6136 N at 0.5 MPa is excessive, a smaller bore would be required outside this series; if you need more power, stepping up to the 160 mm bore yields 10053 N. The included TC trunnion mount utilizes the standardized ISO 15552 mounting interface, ensuring compatibility with existing fixture dimensions. Because this SKU includes the -S magnet, it is fully ready for electronic or reed sensors.
At a 1000 mm stroke, the Ø32 mm rod is highly susceptible to bending under off-axis loads—always use an external linear guide to support the payload. Furthermore, exhausting the air or centering the valve will cause the piston to drift, as the air cushions only decelerate near stroke end rather than locking the rod. Install a pilot-operated check valve or external rod lock if the load must be held in place during an air loss event.
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 SGC125X1000STC FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. The air port size is G1/2.
No, a standard double-acting cylinder drifts when air is lost 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. You must use an external rod lock or pilot-operated check valve to hold a load safely.
