Airtac SGC Standard Cylinder SGC125X145
The AirTAC Airtac SGC Standard Cylinder SGC125X145 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 145mm 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 SGC125X145
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy-duty automation with a 145 mm stroke. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity under large-bore thrust, while the two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread match the 125 mm bore standard.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. The standard TPU seals operate from -20 to +70 C, with a Viton H option available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X145 Is Used
Press Fit Tooling
Drives small bushings and bearings into automotive transmission housings using its 6136 N thrust capacity at 0.5 MPa.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop gate on roller conveyors, absorbing impact with its 40 mm adjustable air cushions.
Carton Flap Folder
Folds heavy corrugated cardboard flaps on large-case packaging lines, utilizing the 145 mm stroke to clear tall boxes.
Is the Airtac SGC Standard Cylinder SGC125X145 the Right Cylinder?
When sizing this 125 mm bore option, stepping down is not possible within the SGC series as this is the smallest available size. If you need more power, the next larger 160 mm bore provides 10053 N of push at 0.5 MPa. This 145 mm stroke falls well under the 1500 mm maximum, so standard side-load concerns are minimal.
Remember that a standard cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end of travel and do not act as a brake. To hold a load securely, install 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 SGC125X145 FAQ
The 125 mm bore yields a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the SGC125X145-S variant for magnetic sensing. It is dimensionally interchangeable per the ISO 15552 mounting interface for standard fixtures.
