Airtac SGC Standard Cylinder SGC125X750
The AirTAC Airtac SGC Standard Cylinder SGC125X750 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 SGC125X750
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore tie-rod cylinder is built for heavy-duty automation. The four steel tie rods clamp the aluminum 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 safely lifts roughly 313 kg vertically with a 2:1 margin.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. The standard TPU seals handle temperatures from -20 to +70 C, with a Viton H option available for 0-150 C environments. Air enters via the G1/2 port, and the ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures.

Where the Airtac SGC Standard Cylinder SGC125X750 Is Used
Pallet Transfer Reject
Pushes heavy pallets off a high-speed sorting line using 6136 N of thrust at 0.5 MPa over a 750 mm reach.
Warehouse Divert Arm
Actuates a long diverting arm in distribution centers, moving boxed inventory across extended conveyor lanes.
Press Ejection
Ejects finished metal parts from a large stamping press, utilizing the full 750 mm stroke to clear the tooling area.
Is the Airtac SGC Standard Cylinder SGC125X750 the Right Cylinder?
When sizing this 125 mm bore unit, stepping down is not an option within the SGC range, but moving up to the 160 mm bore increases thrust to 10053 N at 0.5 MPa. For the 750 mm stroke, providing external guide support is critical to prevent rod bending and manage side loads during extension. Note that a plain 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. To suspend a load safely, 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 SGC125X750 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, and a theoretical maximum of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must purchase the -S variant to use CMSG, DMSG, or EMSG switches. The unit does offer ISO 15552 mounting interface interchangeability for easy fixture integration.
