Airtac SGC Standard Cylinder SGC125X200SH
The AirTAC Airtac SGC Standard Cylinder SGC125X200SH 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 SGC125X200SH
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation. 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. Because it carries the -S option, a built-in piston magnet enables direct mounting of CMSG, DMSG, or EMSG electronic switches for position sensing.
The 125 mm bore uses a G1/2 air port and a 32 mm rod with an M27x2.0 thread. Equipped from the factory with the Viton H seal, this unit operates in environments up to 150 C instead of the standard 70 C limit. 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.

Where the Airtac SGC Standard Cylinder SGC125X200SH Is Used
Press Ejection
Provides the 6136 N push force needed to eject formed metal parts from a hydraulic press bed operating in high-ambient-heat conditions.
Pallet Squaring
Uses the 200 mm stroke to square up heavy inbound pallets on a conveyor line before stretch wrapping, relying on the -S magnet for position feedback.
Mold Clamping
Secures injection mold halves at 150 C using the Viton H seal, delivering reliable clamping force without thermal degradation of the elastomers.
Is the Airtac SGC Standard Cylinder SGC125X200SH the Right Cylinder?
This 200 mm stroke sits comfortably within the 25-1500 mm standard range, but at this length you should support the load with external guide rails to prevent rod bending and premature seal wear. When sizing, note that stepping up to the 160 mm bore increases thrust to 10053 N at 0.5 MPa, while there is no smaller SGC bore below 125 mm. The standard air cushion decelerates the piston near the end caps but does not function as a brake; if air pressure drops, the piston will drift, so add an external rod lock or pilot-operated check valve for suspended 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 SGC125X200SH FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into standard large-bore foot, flange, or trunnion fixtures. The included -S piston magnet allows you to mount CMSG, DMSG, or EMSG switches directly to the barrel.
