About the Airtac SGC Standard Cylinder SGC125X70S
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings serious thrust to compact 70 mm strokes. It features a genuine ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures and standard accessory kits. Four steel tie rods clamp the aluminium barrel to the covers, ensuring high rigidity under heavy loads, while the two-way piston seal maintains an internal oil reservoir for long mechanical life.
The built-in -S piston magnet enables direct mounting of CMSG, DMSG, or EMSG switches for electronic or reed position sensing. With a G1/2 port and a 32 mm rod, 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. Standard TPU seals handle temperatures from -20 to +70 C, with Viton H available for 0-150 C high-heat environments.

Where the Airtac SGC Standard Cylinder SGC125X70S Is Used
Press Fit Tooling
Drives small bushings and bearings into automotive transmission housings, utilizing the 6136 N push force within a tight 70 mm stroke.
Carton Flap Folding
Actuates heavy cardboard flap folders on high-speed packaging lines where the 313 kg vertical lift capacity easily overcomes carton resistance.
Pallet Stopper Gate
Controls heavy pallet flow on roller conveyors by extending a 70 mm stopper block, relying on the steel tie-rod build for repeated impact absorption.
Is the Airtac SGC Standard Cylinder SGC125X70S the Right Cylinder?
When sizing this 125 mm bore, compare your actual load against its 6136 N push and 5734 pull capabilities at 0.5 MPa. If your application demands less force, there is no smaller SGC bore available, so you must throttle the pressure accordingly; if you need substantially more power, step up to the 160 mm bore which provides 10053 N of push at 0.5 MPa. Because this specific SKU includes the -S magnet, you can easily integrate CMSG, DMSG, or EMSG sensors without modifying the assembly.
Keep in mind that a standard double-acting cylinder will drift and cannot hold a load if air pressure drops or the valve is centered, as the adjustable air cushion only decelerates the piston near the stroke ends rather than acting as a brake. For suspended or vertical loads that must remain fixed during a loss of pressure, incorporate 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 SGC125X70S FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa, it delivers 8590 N push and 8028 N pull, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. Additionally, the body is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard foot, flange, or trunnion accessories.
