Airtac SGC Standard Cylinder SGC125X170S
The AirTAC SGC Standard Cylinder SGC125X170S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 170mm 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 SGC125X170S
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious power to automated lines. The SGC125X170S uses a robust tie-rod design where four steel rods clamp the aluminum barrel to the covers, maintaining high rigidity under heavy thrust. It also features a two-way piston seal that retains an oil reservoir for continuous lubrication and extended service life.
Because it is built to the ISO 15552 mounting interface, this unit drops directly into existing large-bore fixtures without custom brackets. The included -S piston magnet enables CMSG, DMSG or EMSG position switches for closed-loop feedback. The G1/2 air port and M27x2.0 rod thread match the 125 mm bore standard.

Where the Airtac SGC Standard Cylinder SGC125X170S Is Used
Press Die Ejection
Ejects formed metal parts from stamping presses using the 6136 N push force, relying on the -S magnet to confirm part clearance before the press cycles.
Pallet Stopper Gate
Acts as a heavy-duty stop gate on roller conveyors, absorbing pallet impacts with its tie-rod construction while position switches track gate status.
Carton Flap Folder
Folds heavy corrugated carton flaps prior to sealing, utilizing the 170 mm stroke to clear the packaging path during retraction.
Is the Airtac SGC Standard Cylinder SGC125X170S the Right Cylinder?
When sizing this 125 mm bore option, compare it against its neighbors: the larger 160 mm bore provides 10053 N push at 0.5 MPa for heavier demands, while there is no smaller SGC variant below 125 mm. This 170 mm stroke length is well within the 1500 mm maximum, keeping the rod side-load risk low without requiring external guides. The standard TPU elastomer seals handle temperatures from -20 to +70 C, though a Viton H option extends this to 0-150 C for hot environments.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the adjustable 40 mm air cushions at both ends only decelerate the piston near stroke end and do not act as a brake. To suspend a vertical load safely during an outage, 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 SGC125X170S 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 accepts standard ISO 15552 foot, flange, and trunnion brackets. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG reed and electronic switches for position detection.
