Airtac SGC Standard Cylinder SGC125X100STC
The AirTAC Airtac SGC Standard Cylinder SGC125X100STC 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 SGC125X100STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder is built around a genuine ISO 15552 tie-rod design. Four steel 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. Plan for about 3682 N of real work at 0.5 MPa, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin.
The Ø125 mm bore uses a G1/2 air port, an M27x2.0 rod thread, and a 40 mm adjustable air cushion at both ends to decelerate the stroke smoothly. Because this SKU includes the -S magnet, it is fully compatible with CMSG, DMSG, and EMSG position switches. The factory TC trunnion mounting interface makes it dimensionally interchangeable with other ISO 15552 fixtures, simplifying machine integration and spares.

Where the Airtac SGC Standard Cylinder SGC125X100STC Is Used
Press Die Ejection
Provides the 6136 N push force needed to eject heavy stamped parts from a 125 mm bore press bed, utilizing the 100 mm stroke to clear the die block safely.
Pallet Stopper Gate
Acts as a robust pneumatic stop gate on high-mass conveyor lines, using the TC trunnion mount to pivot smoothly while absorbing the impact of incoming pallets.
Injection Mold Clamping
Secures intermediate mold halves in automated plastic injection cells, where the CMSG sensors detect the 100 mm extended position to sequence the machine safely.
Is the Airtac SGC Standard Cylinder SGC125X100STC the Right Cylinder?
When sizing this actuator, step down to the smaller SGC bore or up to the Ø160 class (which provides 10053 N push at 0.5 MPa) if your load sits near the boundary. Remember that a standard cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near the end of stroke and does not function as a locking brake. For suspended or vertical loads that must hold position, add an external rod lock or a pilot-operated check valve. The included -S magnet allows seamless sensor integration, and the TC trunnion mount suits pivoting articulated loads.
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 SGC125X100STC FAQ
This Ø125 mm bore model features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
