Airtac SGC Standard Cylinder SGC125X160S
The AirTAC Airtac SGC Standard Cylinder SGC125X160S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGC125X160S
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder brings genuine ISO 15552 mounting-interface interchangeability to heavy automation setups. The 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. With its built-in piston magnet, this -S variant directly supports CMSG, DMSG, and EMSG position switches.
For practical sizing, plan for about 3682 N of real work at 0.5 MPa, or roughly 313 kg lifted vertically with a 2:1 safety margin. The 125 mm bore uses a G1/2 air port and a 32 mm hard-chrome rod, and the standard TPU seals handle temperatures from -20 to +70 C. You can also swap to Viton H seals for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC125X160S Is Used
Press Fit Assembly
Drives bearings or bushings into heavy housings, utilizing the 6136 N push force at 0.5 MPa to seat components reliably without hydraulic fluid.
Pallet Stopper Gate
Acts as a robust 160 mm stroke blocking mechanism on conveyor lines, halting loaded pallets weighing up to 313 kg vertically with a 2:1 margin.
Carton Flap Folder
Executes rapid folding motions on large packaging lines, where the 30-500 mm/s speed range and CMSG sensors ensure precise timing.
Is the Airtac SGC Standard Cylinder SGC125X160S the Right Cylinder?
If you need less force, the next size down does not exist within the SGC large-bore family, making 125 mm the entry point. Stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N. Because this 160 mm stroke falls below the 500 mm side-load threshold, standard mounting options like LB foot, FA flange, or TC trunnion brackets are highly effective without auxiliary guides.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near the stroke end rather than locking it. To suspend a load safely during an outage, integrate an external rod lock or a pilot-operated check valve into your 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 SGC125X160S FAQ
This 125 mm bore model uses a G1/2 air port and delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 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 and shares matching FA flange or TC trunnion footprints. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly onto the barrel for position detection.
