Airtac SGC Standard Cylinder SGC125X1000S
The AirTAC Airtac SGC Standard Cylinder SGC125X1000S 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 SGC125X1000S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminum barrel to the covers, providing the rigidity needed to handle large-bore thrust without flexing. The two-way piston seal maintains an internal oil reservoir for continuous lubrication and extended service life.
Because this variant includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches. For practical sizing, 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. The G1/2 air port feeds the 125 mm bore, driving the 32 mm rod at speeds of 30-500 mm/s.

Where the Airtac SGC Standard Cylinder SGC125X1000S Is Used
Pallet Transfer Line
Pushes heavy loaded pallets across a 1-meter gap between roller conveyors using its 6136 N thrust capacity.
Vertical Lift Gate
Raises a 300 kg mezzanine safety gate, matching the 313 kg vertical lift capability with a safe 2:1 margin.
Press Ejection
Ejects formed metal parts from a hydraulic press over a long 1000 mm reach, utilizing the CMSG sensors for timing.
Is the Airtac SGC Standard Cylinder SGC125X1000S the Right Cylinder?
When sizing this 125 mm bore unit, the SGC series steps up directly to the 160 mm bore for significantly higher thrust (10053 N push at 0.5 MPa), as there is no smaller SGC option below 125 mm. This 1000 mm stroke length requires careful attention to side loads; always use an external guide or rod-end support to prevent rod bending over such a long extension. Although the adjustable air cushions decelerate the piston at both ends, they do not function as a brake. If the air supply drops or the valve centers, the load will drift, so fit an external rod lock or pilot-operated check valve for secure holding.
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 SGC125X1000S FAQ
This 125 mm bore cylinder features a G1/2 air port and a 32 mm rod. It generates 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 force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore fixtures. You can use standard LB foot, FA flange, or TC trunnion mounts, and the included -S magnet enables CMSG, DMSG, and EMSG sensors.
