About the Airtac SGC Standard Cylinder SGC125X1500
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation. 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.
The unit features a 125 mm bore, a 1500 mm stroke, and a G1/2 port. Because this specific 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 Viton H and NBR options available for specialized environments.

Where the Airtac SGC Standard Cylinder SGC125X1500 Is Used
Automated Pallet Transfer
Pushes heavy pallets along a 1.5-meter accumulation line, utilizing the 6136 N push force to overcome sliding friction without stalling.
Vertical Material Lift
Raises tiered storage trays within high-bay racking, safely lifting loads up to 313 kg using a 2:1 safety margin at 0.5 MPa.
Long-Reach Part Ejection
Ejects molded components from a large press bed over a 1500 mm distance, relying on external guides to maintain rod alignment.
Is the Airtac SGC Standard Cylinder SGC125X1500 the Right Cylinder?
When sizing this 125 mm bore option, verify if the 6136 N push at 0.5 MPa provides enough margin, or step up to the 160 mm bore for 10053 N. If your application requires position feedback, select the -S magnet variant to enable CMSG, DMSG, or EMSG sensors. At the maximum standard stroke of 1500 mm, the 32 mm rod is highly susceptible to bending under side loads; always use external guide rails to support the load and prevent rod damage.
Remember that a standard double-acting 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 suspend a vertical 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 SGC125X1500 FAQ
This 125 mm bore cylinder features a G1/2 port and generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into standard large-bore fixtures. The rigid tie-rod construction supports LB foot, FA flange, and TC trunnion mounts, but this non-S SKU cannot host magnetic sensors.
