About the Airtac SGC Standard Cylinder SGC125X200STC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious power to automated lines. The Ø125 mm bore is structurally secured by four steel tie rods that clamp the aluminum barrel to the covers, ensuring high rigidity under heavy thrust. Because it adheres to the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without alignment headaches.
Equipped with a built-in piston magnet (-S), the unit supports CMSG, DMSG, and EMSG switches for precise end-position detection. The two-way piston seal maintains an internal oil reservoir for continuous lubrication and extended seal life. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. It features a G1/2 air port and a 40 mm adjustable air cushion at both ends to decelerate the payload smoothly.

Where the Airtac SGC Standard Cylinder SGC125X200STC Is Used
Pallet Diversion
Actuates heavy-duty routing gates on 1500 mm conveyor lines, using the 6136 N thrust to push fully loaded pallets onto secondary packaging tracks.
Press Ejection
Ejects dense stamped metal parts from a 200-ton press bed, relying on the 40 mm adjustable air cushions to soften the impact at the end of the 200 mm extension.
Vertical Lift Gate
Raises and lowers a 280 kg mezzanine safety gate, fitting well within the 313 kg vertical lift capacity calculated with a 2:1 safety margin at 0.5 MPa.
Is the Airtac SGC Standard Cylinder SGC125X200STC the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down is not an option within the SGC family as 125 mm is the smallest, while moving up to the Ø160 bore increases the 0.5 MPa push force significantly to 10053 N. This specific SKU includes a TC trunnion mount, which pairs with the ISO 15552 interface to handle pivoting loads, and the -S magnet enables electronic position sensing. At a 200 mm stroke, side-load risks are moderate, but always ensure the load is guided to prevent rod bending.
Remember that a standard pneumatic cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The integrated air cushions only serve to decelerate the rod near the stroke ends, acting as a buffer rather than a mechanical brake. To suspend a load safely during an emergency stop, incorporate an external rod lock or a pilot-operated check valve into your 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 SGC125X200STC FAQ
This Ø125 mm bore model features a G1/2 air port and a M27x2.0 rod thread. It generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in magnet compatible with CMSG, DMSG, and EMSG reed or electronic switches. Furthermore, its tie-rod construction conforms strictly to ISO 15552 mounting interface dimensions, allowing it to use standard TC trunnion, LB foot, or FA flange accessories without modification.
