Airtac SGC Standard Cylinder SGC125X220S
The AirTAC Airtac SGC Standard Cylinder SGC125X220S 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 SGC125X220S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy-duty automation 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. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches. The 125 mm bore utilizes a G1/2 air port, an M27x2.0 rod thread, and a 40 mm adjustable air cushion at both ends to decelerate the payload smoothly.

Where the Airtac SGC Standard Cylinder SGC125X220S Is Used
Press Ejection
Provides the robust 6136 N push stroke needed to eject formed metal parts from heavy stamping presses reliably.
Pallet Stops
Acts as a high-strength stopper gate on heavy-duty roller conveyors to halt loaded pallets weighing up to 313 kg.
Clamp Actuators
Secures large automotive castings during machining operations using CA or CB clevis mounting accessories.
Is the Airtac SGC Standard Cylinder SGC125X220S the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-frame family, offering 6136 N push at 0.5 MPa. If your application requires less force, no smaller SGC bore exists and you must look outside this series; if you need more power, stepping up to the 160 mm bore provides 10053 N. The 220 mm stroke falls under the 500 mm threshold, keeping side-load risks low, but always ensure rigid mounting using LB foot, FA flange, or TC trunnion brackets.
Remember that a standard cylinder drifts if air pressure drops or the valve is centered, as the end cushions only slow the piston near stroke completion and never act as a brake. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SGC125X220S 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, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard large-bore fixtures and brackets. The included -S magnet enables CMSG, DMSG, and EMSG electronic or reed switches for position sensing.
