Airtac SGC Standard Cylinder SGC125X700
The AirTAC Airtac SGC Standard Cylinder SGC125X700 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 700mm 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 SGC125X700
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles long 700 mm strokes with a 125 mm bore. Four steel tie rods clamp the aluminum barrel to the covers, providing high rigidity under heavy thrust, while the two-way piston seal maintains an internal oil reservoir for extended lifespan. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The unit features a G1/2 port, an M27x2.0 rod thread, and adjustable 40 mm air cushions at both ends to decelerate the piston smoothly. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SGC Standard Cylinder SGC125X700 Is Used
Pallet Transfer Diversion
Pushes heavy wood or steel pallets sideways off a high-speed main conveyor line, utilizing the 700 mm stroke to clear adjacent machinery.
Press Roll Lowering
Lowers a heavy industrial press roll in a paper mill, using the adjustable air cushions to prevent harsh impact at the bottom of the 700 mm travel.
Automated Storage Retrieval
Acts as a long-reach pusher in automated warehousing, sliding standardized totes from a roller conveyor into a deep storage rack compartment.
Is the Airtac SGC Standard Cylinder SGC125X700 the Right Cylinder?
When sizing this 125 mm bore model, verify if the 6136 N push force at 0.5 MPa is sufficient; if more thrust is required, stepping up to the 160 mm bore yields 10053 N. Since 125 mm is the smallest SGC option, there is no smaller standard bore in this series to drop down to. For position feedback, you would need to select the -S magnet variant, as this SKU cannot accept a sensor.
Because the 700 mm stroke is substantial, external guide rails are strongly recommended to prevent rod bending and side-load damage during extension. Furthermore, the air cushions only decelerate the piston near the stroke ends and do not function as a brake; if the air supply is lost or the valve is centered, the piston will drift. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 SGC125X700 FAQ
The 125 mm bore provides 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 a magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must select the -S variant of this model. Without the magnet, you will need external mechanical or proximity sensors for position detection.
