Airtac SGC Standard Cylinder SGC125X250TC
The AirTAC Airtac SGC Standard Cylinder SGC125X250TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 250mm 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 SGC125X250TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation tasks. 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. Plan for about 3682 N of real work at 0.5 MPa, which means it lifts roughly 313 kg vertically with a 2:1 safety margin.
The 125 mm bore uses a G1/2 air port and an M27x2.0 piston rod thread. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. Adjustable air cushions at both ends absorb kinetic energy near the stroke limits, and the default TPU seal handles temperatures from -20 to +70 C.

Where the Airtac SGC Standard Cylinder SGC125X250TC Is Used
Press Ejection
Provides the robust 6136 N push required to eject formed metal parts from heavy stamping presses.
Pallet Diversion
Actuates heavy-duty diverter arms on conveyor lines to route loaded pallets using the TC trunnion pivot.
Material Lift Gates
Raises and lowers industrial safety gates on loading docks, easily handling loads up to 313 kg vertically.
Is the Airtac SGC Standard Cylinder SGC125X250TC the Right Cylinder?
When sizing this 125 mm bore unit, consider the neighbouring SGC bores to match your exact load: the larger SGC160 provides 10053 N of push at 0.5 MPa if you need more power, while there is no smaller SGC option below 125 mm. The integrated TC trunnion mount suits pivoting articulations, but ensure your external mechanism supports the rod laterally, especially over this 250 mm stroke, to prevent excessive side-load bending.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the end cushions only decelerate the piston and do not act as a brake. To suspend a vertical load safely, fit an external rod lock or a 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 SGC125X250TC FAQ
This 125 mm bore model features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select an -S variant to use CMSG, DMSG, or EMSG switches. It uses a standard ISO 15552 mounting interface for mechanical fixtures.
