Airtac SGC Standard Cylinder SGC125X1250
The AirTAC Airtac SGC Standard Cylinder SGC125X1250 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1250mm 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 SGC125X1250
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles large-bore automation with a 1250 mm stroke. 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. A G1/2 port supplies the 32 mm chrome-plated rod.
Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. 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 TPU seal handles -20 to +70 C, with a Viton H option for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X1250 Is Used
Pallet Transfer Pusher
Pushes heavy pallets along a 1250 mm conveyor lane using 6136 N of 0.5 MPa thrust, relying on external guides to absorb side loads.
Warehouse Divert Gate
Actuates a long diverting gate in distribution centers, where the 1250 mm stroke moves parcels between sorting lanes.
Automated Panel Stacking
Indexes sheet materials along a 1.25-meter path, using the 40 mm adjustable air cushions to decelerate the payload smoothly.
Is the Airtac SGC Standard Cylinder SGC125X1250 the Right Cylinder?
This 125 mm bore sits at the lower end of the SGC range; stepping up to the 160 mm bore yields 10053 N at 0.5 MPa if your application needs more thrust. The 1250 mm stroke demands external guide support to prevent rod bending under side loads. Without a -S magnet, position sensing is unavailable. Note that exhausting the air causes the piston to drift, so fit an external rod lock or pilot-operated check valve for vertical load holding.
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 SGC125X1250 FAQ
The G1/2 port feeds a 32 mm rod. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
No, this specific SKU lacks a piston magnet. You must order the -S variant to mount CMSG, DMSG, or EMSG switches. The ISO 15552 mounting interface ensures it drops into standard large-bore fixtures.
