Airtac SGC Standard Cylinder SGC125X750S
The AirTAC Airtac SGC Standard Cylinder SGC125X750S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 750mm 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 SGC125X750S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles long-stroke automation with ease. 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 extended service life. The G1/2 port and M27x2.0 rod thread match the 125 mm bore standard.
Because the code ends in S, a built-in piston magnet enables 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 Viton H seal option can elevate operating temperatures from the standard -20 to +70 C range up to 150 C.

Where the Airtac SGC Standard Cylinder SGC125X750S Is Used
Automated Pallet Diversion
Uses the 750 mm stroke to push heavy pallets cleanly across a transfer line, relying on the 6136 N push force at 0.5 MPa to overcome friction.
Vertical Lift Gate Actuation
Raises and lowers material handling gates, safely lifting parts weighing up to 313 kg with a 2:1 safety margin using the integrated magnet for end-of-stroke confirmation.
Large Press Ejection
Ejects formed metal components from a press bed, utilizing the four steel tie rods to maintain structural rigidity under sudden impact loads.
Is the Airtac SGC Standard Cylinder SGC125X750S the Right Cylinder?
Stepping down to a smaller bore is not an option within the SGC family, but stepping up to the 160 mm bore provides 10053 N of push at 0.5 MPa if your application outgrows this unit. At a 750 mm stroke, the 32 mm rod requires external guide support to prevent side-load bending and premature seal wear. Remember that the adjustable 40 mm air cushion only decelerates the piston near stroke end; it does not lock the load. For vertical or suspended loads that must hold position during air loss, add an external rod lock or pilot-operated check valve.
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 SGC125X750S 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, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, dropping into standard large-bore fixtures. The included S magnet supports CMSG, DMSG, and EMSG switches for electronic or reed position sensing.
