Airtac SGC Standard Cylinder SGC125X200S
The AirTAC Airtac SGC Standard Cylinder SGC125X200S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGC125X200S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminium barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for around 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin.
The included -S piston magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position detection. This 125 mm bore model uses a G1/2 air port, an M27x2.0 rod thread, and adjustable 40 mm air cushions at both ends to decelerate the payload smoothly. It operates at speeds of 30-500 mm/s, and the standard TPU seals handle temperatures from -20 to +70 C, with a Viton H option available for up to 150 C.

Where the Airtac SGC Standard Cylinder SGC125X200S Is Used
Press Ejection Systems
Provides the robust 6136 N push force needed to eject formed metal parts from heavy stamping presses, using the 200 mm stroke to fully clear the die area.
Pallet Diverting Arms
Actuates heavy diverter arms on packaging lines to route loaded pallets, relying on the ISO 15552 mounting interface for rigid fixture attachment.
Lift Gate Actuation
Raises and lowers industrial loading dock gates, where the built-in -S magnet works with DMSG sensors to confirm gate position and prevent collisions.
Is the Airtac SGC Standard Cylinder SGC125X200S the Right Cylinder?
This 125 mm bore is the entry point of the SGC large-frame family, offering 6136 N push at 0.5 MPa. If your application requires less force, you would step out of this series to a smaller standard profile, but if you need more thrust, the next size up is the 160 mm bore delivering 10053 N at 0.5 MPa. Because this unit has the -S magnet, it is ready for CMSG, DMSG or EMSG electronic switches; a plain SKU without the S suffix cannot accept a sensor. Mounting options include LB foot, FA flange, CA clevis and TC trunnion brackets.
With a 200 mm stroke, the piston rod travels far enough that you should verify side-load conditions and guide external mechanisms to prevent rod bending. Remember that the adjustable air cushion only decelerates the piston near the end caps; it does not act as a brake. If the air supply is lost or the valve is centred, the piston will drift, so fit an external rod lock or pilot-operated check valve for applications requiring strict position holding.
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 SGC125X200S FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, the SGC series is dimensionally interchangeable per the ISO 15552 mounting interface, meaning it drops into the same fixture and accessory hole patterns as any standard ISO 15552 large-bore cylinder. The rigid four-tie-rod construction ensures the barrel and covers stay securely clamped under high thrust loads.
