About the Airtac SGC Standard Cylinder SGC125X190
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore tie-rod cylinder handles heavy automation tasks. It features a 190 mm stroke and a G1/2 air port. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while a two-way piston seal maintains an internal oil reservoir for long service life.
Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. The standard TPU seals operate from -20 to +70 C, though Viton H options extend this to 150 C. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.

Where the Airtac SGC Standard Cylinder SGC125X190 Is Used
Press Die Ejection
Ejects formed metal parts from a 125-ton stamping press using the 6136 N push force to overcome die friction.
Pallet Stopper Gate
Acts as a heavy-duty stop gate on a conveyor line, absorbing pallet impacts with its 40 mm adjustable air cushions.
Plastic Mold Clamp
Secures injection molding tooling halves during low-pressure mold setup sequences using its 190 mm stroke.
Is the Airtac SGC Standard Cylinder SGC125X190 the Right Cylinder?
As the smallest bore in the SGC family, the 125 mm size offers 6136 N push at 0.5 MPa, with the next size up being the 160 mm bore delivering 10053 N. If air pressure drops or the valve centers, the piston drifts since the end cushions only decelerate motion near stroke ends rather than locking the load; use an external rod lock or pilot-operated check valve for secure holding. Without the -S magnet, position sensing is unavailable on this unit. The 190 mm stroke is safely below the 500 mm threshold, keeping side-load and rod-bending risks minimal without auxiliary guides.
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 SGC125X190 FAQ
The SGC125X190 delivers 6136 N push and 5734 N pull at 0.5 MPa, or 8590 N push and 8028 N pull at 0.7 MPa. Its theoretical maximum force is 1251 kgf at 1.0 MPa. The air port size is G1/2.
No, this specific SKU lacks the -S magnet option, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. It uses a tie-rod build dimensionally interchangeable per the ISO 15552 mounting interface.
