Airtac SGC Standard Cylinder SGC125X1080
The AirTAC Airtac SGC Standard Cylinder SGC125X1080 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1080mm 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 SGC125X1080
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator utilizes a genuine ISO 15552 mounting interface to drop directly into existing standard fixtures. The four steel tie rods clamp the aluminum barrel to the covers, providing high rigidity under heavy thrust, 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.
Equipped with a G1/2 port and a 32 mm hard-chrome rod, the unit features adjustable 40 mm air cushions at both ends to manage impact. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. The generous 1080 mm stroke requires external guide support to prevent rod bending under side loads.

Where the Airtac SGC Standard Cylinder SGC125X1080 Is Used
Pallet Transfer Pusher
Uses the 6136 N thrust to push heavy pallets sideways between adjacent roller conveyors in packaging lines.
Vertical Lift Gate
Raises a 300 kg mezzanine safety gate using the 1080 mm stroke, relying on external linear guides to prevent rod bending.
Press Ejector
Ejects stamped metal parts from a press bed, utilizing the adjustable 40 mm cushions to soften end-of-stroke impact.
Is the Airtac SGC Standard Cylinder SGC125X1080 the Right Cylinder?
When sizing this 125 mm bore option, compare it against its neighbors: step down to avoid oversizing, or move up if thrust is insufficient. The next size down does not exist in the SGC series, but stepping up to the 160 mm bore yields 10053 N push at 0.5 MPa. At 1080 mm, the extended rod is highly susceptible to bending forces, so an external linear guide is mandatory to support the load. Note that air cushions only decelerate the piston near stroke end; they do not function as a brake. To prevent drifting when air is lost or the valve is centered, 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 SGC125X1080 FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push / 5734 N pull at 0.5 MPa, and 8590 N push / 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing.
