Airtac SGC Standard Cylinder SGC125X730S
The AirTAC Airtac SGC Standard Cylinder SGC125X730S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 730mm 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 SGC125X730S
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings large-bore power to demanding setups. The Ø125 mm bore uses a G1/2 air port and an M27x2.0 rod thread. 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. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
With a 730 mm stroke, plan for roughly 3682 N of real work at 0.5 MPa, which equates to lifting about 313 kg vertically with a 2:1 safety margin. The included -S piston magnet enables CMSG, DMSG or EMSG switches for position sensing. Standard TPU seals handle temperatures from -20 to +70 C, with Viton H available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X730S Is Used
Automated Pallet Diversion
Uses the 730 mm stroke to push heavy pallets cleanly across transfer lines, relying on the 6136 N push force at 0.5 MPa to overcome sliding friction.
Vertical Material Lift Gate
Actuates large loading dock gates where the -S magnet allows DMSG sensors to confirm fully open positions before forklifts enter.
Press Ejection System
Ejects finished metal parts from a hydraulic press, using the tie-rod rigidity to withstand repetitive high-impact lateral stresses.
Is the Airtac SGC Standard Cylinder SGC125X730S the Right Cylinder?
When sizing this 125 mm bore, compare it against its neighbors: stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa, while there is no smaller SGC option below 125 mm. For this 730 mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads during long extensions. Remember that a plain cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end of travel. To hold a suspended load safely, add 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 SGC125X730S FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. 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, so it fits standard FA flanges or TC trunnions. The built-in -S magnet supports CMSG, DMSG and EMSG switches for electronic or reed position sensing.
