Airtac SGC Standard Cylinder SGC125X110S
The AirTAC Airtac SGC Standard Cylinder SGC125X110S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 110mm 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 SGC125X110S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy-duty automation with ease. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir to ensure long service life. The G1/2 port and M27x2.0 rod thread equip this 125 mm bore unit for demanding cycles.
Because it carries the -S suffix, a built-in piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing. Plan for about 3682 N of real work at 0.5 MPa, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin. The standard TPU seal handles temperatures from -20 to +70 C, with a Viton H option available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X110S Is Used
Press Fit Assembly
Drives bearings into heavy housings on an automated machining line, utilizing the 6136 N push force to seat components accurately.
Pallet Stopper Gate
Acts as a heavy-duty stopping barrier on a conveyor system, raising and lowering to block 300 kg loaded pallets securely.
Plastic Injection Mold
Operates a large core pull mechanism on an injection molding machine, relying on the rigid tie-rod frame to withstand cyclic loads.
Is the Airtac SGC Standard Cylinder SGC125X110S the Right Cylinder?
Choosing this 110 mm stroke model means sizing around its 6136 N push capacity at 0.5 MPa. If your application requires less force, stepping down is not possible within the SGC range as 125 mm is the smallest available bore. If you need significantly more power, the 160 mm bore provides 10053 N of push force. For any stroke length at or above 500 mm, you must support the load with external guides to prevent rod bending and premature seal wear.
Remember that a standard pneumatic cylinder cannot hold a load when air pressure is lost or the valve is centered, as the piston will drift and the end cushions only decelerate motion near the stroke limits. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Furthermore, ensure you pair this -S variant with compatible CMSG, DMSG, or EMSG sensors, as non-magnet versions cannot accept them.
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 SGC125X110S 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, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into standard large-bore fixtures like LB foot or TC trunnion brackets. The -S suffix denotes a built-in magnet, allowing you to mount CMSG, DMSG, or EMSG electronic or reed switches for position detection.
