Airtac SGC Standard Cylinder SGC200X400STC
The AirTAC Airtac SGC Standard Cylinder SGC200X400STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 400mm stroke, G3/4 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 SGC200X400STC
Delivering 15708 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy-duty automation. The Ø200 mm bore uses a G3/4 air port and a Ø40 mm hard-chrome rod with an M36x2.0 thread. 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. The -S suffix means a piston magnet is installed, enabling CMSG, DMSG, or EMSG reed and electronic switches for position sensing.
For real-world sizing, plan for about 9425 N of actual work at 0.5 MPa, which equates to lifting roughly 801 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, though a Viton H option extends this to 0-150 C. Adjustable 50 mm air cushions at both ends absorb kinetic energy near stroke end to protect the mechanics.

Where the Airtac SGC Standard Cylinder SGC200X400STC Is Used
Press Ejection
Knocks heavy stamped metal parts out of a 200-ton press bed, using the 21991 N push force at 0.7 MPa to break vacuum grease adhesion.
Pallet Stopper
Acts as a heavy-duty end-stop on a 1000 kg capacity roller conveyor, absorbing the impact of incoming pallets via its 50 mm adjustable air cushions.
Mold Clamping
Secures large injection mold halves during material injection, applying up to 3204 kgf of theoretical clamping force at the maximum 1.0 MPa pressure.
Is the Airtac SGC Standard Cylinder SGC200X400STC the Right Cylinder?
This 400 mm stroke model sits between the smaller Ø160 bore (10053 N push @0.5 MPa) and the larger Ø250 bore (24543 N push @0.5 MPa), giving you a clear upgrade path if your air pressure is marginal. The included TC trunnion mount pivots centrally to handle lateral rod loads better than a fixed flange. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors without further modification.
At 400 mm of travel, side loads become a concern, so guide the load externally to prevent rod bending and premature seal wear. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the air cushions only decelerate the piston near the stroke ends rather than locking it. Use an external rod lock or pilot-operated check valve if you need to hold a suspended load safely.
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 SGC200X400STC FAQ
This Ø200 mm bore cylinder features a G3/4 air port and delivers 15708 N push / 15079 N pull at 0.5 MPa, 21991 N push / 21110 N pull at 0.7 MPa, and a theoretical maximum of 3204 kgf at 1.0 MPa.
Yes, the tie-rod construction is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard foot, flange, clevis, or TC trunnion accessories. The -S suffix indicates a built-in piston magnet ready for CMSG, DMSG, or EMSG position switches.
