Airtac SGC Standard Cylinder SGC125X70
The AirTAC Airtac SGC Standard Cylinder SGC125X70 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 70mm 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 SGC125X70
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder brings large-bore power to compact 70 mm stroke movements. Its 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. The design follows the ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures. This specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG or EMSG position switches without changing to a sensed variant. Equipped with a G1/2 port and an M27x2.0 rod thread, it operates at speeds between 30 and 500 mm/s. 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 SGC125X70 Is Used
Press Fit Tooling
Drives small bushings into automotive transmission housings, utilizing the 6136 N push force at 0.5 MPa to seat components reliably within the 70 mm travel.
Carton Flap Folding
Actuates heavy-duty cardboard flap folders on high-speed packaging lines, where the compact 70 mm stroke ensures rapid cycling without excessive rod overhang.
Pallet Stopper Gate
Controls heavy pallet flow on roller conveyors by extending a 70 mm stopper blade, relying on the rigid four-tie-rod build to absorb repeated impact loads.
Is the Airtac SGC Standard Cylinder SGC125X70 the Right Cylinder?
As the smallest bore in the SGC family, the 125 mm option provides a baseline 6136 N push force at 0.5 MPa; stepping up to the 160 mm bore increases that output to 10053 N. When integrating this 70 mm stroke model, note that the standard air cushion only decelerates the piston near the end of travel and does not function as a braking mechanism. If the machinery loses air pressure or the valve is centred, the piston will drift, so an external rod lock or pilot-operated check valve is required to hold a suspended load securely. Furthermore, because this configuration omits the -S magnet, you must select a sensed version if your application requires CMSG, DMSG or EMSG switches for end-of-stroke confirmation.
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 SGC125X70 FAQ
The SGC125X70 delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N and the pull force is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa, and the air port size is G1/2.
No, this specific SKU does not include the -S magnet option, so it cannot support CMSG, DMSG or EMSG switches. You must select the -S variant of this ISO 15552 tie-rod cylinder to enable magnetic position sensing.
