Airtac SGC Standard Cylinder SGC125X50TC
The AirTAC Airtac SGC Standard Cylinder SGC125X50TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 50mm 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 SGC125X50TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator handles heavy-duty automation tasks with ease. The four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long-term lubrication. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom brackets. The 125 mm bore utilizes a G1/2 air port and a 32 mm hard-chrome rod. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing.

Where the Airtac SGC Standard Cylinder SGC125X50TC Is Used
Pallet Diverters
Uses the 5734 N pull force to push heavy pallets sideways onto adjacent roller lanes in high-throughput packaging lines.
Press Ejection
Short 50 mm stroke rapidly ejects stamped metal parts from a press bed, leveraging the rigid tie-rod build to absorb high impact shocks.
Gate Actuation
Operates heavy industrial loading dock gates where the TC trunnion mount accommodates slight mechanical misalignment during pivoting.
Is the Airtac SGC Standard Cylinder SGC125X50TC the Right Cylinder?
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa provides adequate thrust, or if stepping up to the 160 mm bore (10053 N push) is necessary for heavier loads. As this is the smallest SGC bore, there is no smaller standard option within the series. The integrated TC trunnion mount provides a pivoting centerline for articulating mechanisms.
Remember that a standard cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it. To suspend a load safely, install an external rod lock or a pilot-operated check valve. For position feedback, select the -S magnet variant instead of this non-magnet model.
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 SGC125X50TC FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, and 8590 N push / 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select an SGC125X50TC-S variant to enable CMSG, DMSG, or EMSG magnetic switches for position detection.
