Airtac SGC Standard Cylinder SGC125X150SFTC
The AirTAC Airtac SGC Standard Cylinder SGC125X150SFTC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGC125X150SFTC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator is built around a genuine ISO 15552 tie-rod architecture. Four steel rods clamp the aluminium barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir to maximize service life. The integrated FTC trunnion mounting matches standardized ISO 15552 interface dimensions, allowing a direct drop into existing heavy-duty fixtures.
Equipped with a piston magnet, this unit supports CMSG, DMSG, and EMSG position switches for automated feedback. Plan for roughly 3682 N of actual work at 0.5 MPa, which translates to lifting about 313 kg vertically with a 2:1 safety margin. The G1/2 air port and M27x2.0 rod thread streamline plumbing and clevis attachments across the 150 mm stroke.

Where the Airtac SGC Standard Cylinder SGC125X150SFTC Is Used
Press Die Ejection
Provides the 6136 N push stroke required to eject formed metal panels from heavy stamping presses.
Pallet Dispenser
Separates empty pallets on automated packaging lines, handling vertical lifts up to 313 kg with a safe margin.
Wood Board Clamping
Secures large composite wood sheets during cutting operations using the rigid four-tie-rod barrel design.
Is the Airtac SGC Standard Cylinder SGC125X150SFTC the Right Cylinder?
When sizing this 125 mm bore option, compare its 6136 N output at 0.5 MPa against the next size up: the 160 mm bore provides 10053 N for heavier cycles. As the smallest bore in the SGC family, there is no smaller standard model below it. The included -S magnet enables CMSG, DMSG, or EMSG sensors, and the FTC trunnion mount handles pivoting loads. Note that a standard double-acting cylinder drifts when air pressure is lost or a valve is centered; the adjustable 40 mm air cushions only decelerate the piston near stroke ends rather than locking it. Use an external rod lock or pilot-operated check valve if the application requires strict load 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 SGC125X150SFTC FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, the tie-rod construction is dimensionally interchangeable per the ISO 15552 mounting interface, so it fits standard large-bore fixtures and the built-in FTC trunnion. The -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches.
