Airtac SGC Standard Cylinder SGC125X220STC
The AirTAC SGC Standard Cylinder SGC125X220STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 220mm 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 SGC125X220STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles substantial workloads. The 125 mm bore utilizes a genuine ISO 15552 mounting interface, dropping directly into existing large-bore fixtures and saving engineering time on spares.
Four steel tie rods clamp the aluminum barrel to the covers for high rigidity under heavy thrust, while the two-way piston seal maintains an internal oil reservoir for long service life. Because the -S suffix equips the piston with a magnet, you can track position with CMSG, DMSG, or EMSG switches.

Where the Airtac SGC Standard Cylinder SGC125X220STC Is Used
Press Fit Assembly
Drives bearings into heavy housings using the 6136 N push force at 0.5 MPa, with CMSG sensors confirming the press stroke.
Pallet Stopper Gate
Acts as a robust 220 mm stroke stop gate on conveyor lines, absorbing kinetic energy via the 40 mm adjustable air cushions.
Mold Clamping Arm
Swings into place via the TC trunnion mount to secure injection mold halves, lifting components weighing up to 313 kg safely.
Is the Airtac SGC Standard Cylinder SGC125X220STC the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-bore range; if your task needs less force, you must step outside the SGC family, while heavier loads require stepping up to the 160 mm bore (10053 N push at 0.5 MPa). The TC trunnion mount specified here suits pivoting loads, but remember a plain cylinder drifts when air is lost or the valve is centered—the adjustable air cushion only decelerates the piston near stroke end, so install an external rod lock or pilot-operated check valve for secure load holding. With a 220 mm stroke, ensure adequate guidance to prevent rod bending under side 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 SGC125X220STC FAQ
This 125 mm bore cylinder features a G1/2 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 of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so standard large-bore accessories fit perfectly. The robust tie-rod build clamps the barrel to the covers, and the included -S magnet supports CMSG, DMSG, or EMSG sensors.
