Airtac SGC Standard Cylinder SGC125X100
The AirTAC Airtac SGC Standard Cylinder SGC125X100 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGC125X100
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy automation tasks with ease. 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.
Featuring a 125 mm bore, a 32 mm hard-chrome rod, and a G1/2 port, the SGC125X100 operates at speeds of 30-500 mm/s. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X100 Is Used
Press Fit Assembly
Drives heavy bearings into automotive housings, utilizing the 6136 N push force to seat components precisely without hydraulic fluid.
Pallet Squaring Stop
Acts as a heavy-duty end stop on high-speed packaging conveyors, absorbing kinetic impact using the 40 mm adjustable air cushion.
Injection Mold Clamping
Provides auxiliary holding pressure on large mold halves, taking advantage of the rigid four tie-rod construction under load.
Is the Airtac SGC Standard Cylinder SGC125X100 the Right Cylinder?
When sizing this 125 mm bore model, verify if the 6136 N push force at 0.5 MPa offers adequate headroom for your fixture. If your application demands less power, stepping down to a smaller bore might be necessary, as the SGC series starts at 125 mm. Conversely, if you need substantially more thrust, the 160 mm bore provides 10053 N at 0.5 MPa. The 100 mm stroke keeps the rod compact, minimizing side-load bending concerns.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Furthermore, since this base configuration has no magnet, you must select an -S variant if your control system requires CMSG, DMSG, or EMSG electronic sensors.
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 SGC125X100 FAQ
The SGC125X100 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. It uses a G1/2 air port and features a 32 mm piston rod with an M27x2.0 thread.
Yes, the tie-rod build is dimensionally interchangeable per the ISO 15552 mounting interface, accepting standard LB, FA, CA, and TC mounts. However, because this SKU lacks the -S magnet, it cannot support CMSG, DMSG, or EMSG switches; you must specify an -S model for sensing.
