Airtac SGC Standard Cylinder SGC125X200SFTC
The AirTAC Airtac SGC Standard Cylinder SGC125X200SFTC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGC125X200SFTC
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 for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread handle the 125 mm bore airflow, and the included magnet enables CMSG, DMSG, or EMSG position switches.
Because the theoretical maximum is 1251 kgf at 1.0 MPa, plan for about 3682 N of real work at 0.5 MPa, which lifts roughly 313 kg vertically with a 2:1 margin. The FTC trunnion mount simplifies integration, and the adjustable 40 mm air cushions at both ends decelerate the piston smoothly. For high-temperature environments up to 150 C, specify the Viton H seal option instead of the standard TPU.

Where the Airtac SGC Standard Cylinder SGC125X200SFTC Is Used
Press Fit Assembly
Drives bearings into heavy housings on automotive machining lines, utilizing the 6136 N push force at 0.5 MPa for reliable insertion.
Pallet Stopping Gate
Controls heavy pallet flow on conveyor transfers using the FTC trunnion mount to absorb high side-load moments during deceleration.
Carton Flap Folder
Folds large corrugated flaps on bulk packaging equipment, where the 200 mm stroke and smooth end-cushioning prevent crushing.
Is the Airtac SGC Standard Cylinder SGC125X200SFTC the Right Cylinder?
When sizing this 200 mm stroke unit, verify if the next bore down or up fits better: there is no smaller SGC bore, but the 160 mm bore offers 10053 N push at 0.5 MPa if you need more power. For holding a load vertically, remember that the air cushion only decelerates the piston near stroke end and does not act as a brake; the piston will drift if air is lost or the valve is centered, so add an external rod lock or pilot-operated check valve. The built-in -S magnet allows seamless sensor integration. At 200 mm, side loads are minimal, but always guide the rod to prevent bending.
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 SGC125X200SFTC FAQ
The 125 mm bore has a G1/2 port. It delivers 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 of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so standard large-bore fixtures and the FTC trunnion accessory fit perfectly. The included -S magnet allows you to mount CMSG, DMSG, or EMSG switches for position detection.
