Airtac SGC Standard Cylinder SGC125X1000N
The AirTAC Airtac SGC Standard Cylinder SGC125X1000N 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 SGC125X1000N
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 rigidity, while the two-way piston seal maintains an internal oil reservoir for extended service life. Because this SKU uses an NBR seal, it is built for standard industrial temperatures rather than the high-heat Viton range. Plan for about 3682 N of real work at 0.5 MPa, which means it lifts roughly 313 kg vertically with a 2:1 safety margin.
This model features a G1/2 port, an M27x2.0 rod thread, and 40 mm adjustable air cushions at both ends to manage piston deceleration. Note that this specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG, or EMSG magnetic switches for position sensing. If your automation sequence requires end-of-stroke confirmation, you must select the -S variant instead.

Where the Airtac SGC Standard Cylinder SGC125X1000N Is Used
Pallet Transfer Line
Pushes heavy pallets along a 1000 mm stroke with 3682 N of safe working force, relying on external guides to support the long rod extension.
Vertical Material Lift
Raises 313 kg components vertically using the 125 mm bore, requiring a pilot-operated check valve to prevent dropping when air pressure is lost.
Press Ejection System
Ejects finished parts from a molding press, using the 40 mm adjustable air cushions to absorb the impact at the end of the 1000 mm stroke.
Is the Airtac SGC Standard Cylinder SGC125X1000N the Right Cylinder?
When sizing this large-bore actuator, compare it against its neighbors: the larger SGC160 bore pushes 10053 N at 0.5 MPa, while there is no smaller SGC bore below 125 mm. If your application demands 1000 mm of travel, remember that a plain cylinder does not hold its load when air is lost or the valve is centered—the piston will drift, and the air cushion only decelerates near stroke end, so install an external rod lock or pilot-operated check valve for secure holding.
Furthermore, extending a 32 mm rod over a 1000 mm stroke introduces side-load and rod-bending risks. You must use an external guide or stopper to prevent cantilevered loads from damaging the rod seals. The NBR seal option on this unit suits standard -20 to +70 C environments, and mounting options include LB foot, FA flange, or TC trunnion styles to fit your ISO 15552 fixtures.
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 SGC125X1000N FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
No, because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG switches. You would need to select the -S variant for magnetic sensing. The ISO 15552 mounting interface ensures it drops into standard large-bore fixtures.
