Airtac SGC Standard Cylinder SGC125X230
The AirTAC Airtac SGC Standard Cylinder SGC125X230 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 230mm 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 SGC125X230
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles substantial linear motion tasks. It features a 125 mm bore, a 230 mm stroke, and a G1/2 air port. Four steel tie rods clamp the aluminum barrel to the covers, ensuring high rigidity under heavy thrust, while a two-way piston seal maintains an internal oil reservoir for long service life.
Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. Plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac SGC Standard Cylinder SGC125X230 Is Used
Press Fit Assembly
Drives bearings or bushings into heavy machinery housings, utilizing the 6136 N push force at 0.5 MPa to seat components reliably.
Pallet Stopper Gate
Acts as a robust blocking mechanism on conveyor lines, extending 230 mm to halt pallets weighing up to 313 kg before downstream processing.
Plastic Mould Ejection
Provides the linear thrust required to eject formed plastic parts from large injection moulding tools, benefiting from the rigid tie-rod construction.
Is the Airtac SGC Standard Cylinder SGC125X230 the Right Cylinder?
When sizing this 125 mm bore unit, verify your actual load requirements against its 6136 N push capacity at 0.5 MPa. If your application demands less force, dropping down is not an option within the SGC series as this is the smallest available bore; stepping up to the 160 mm bore yields 10053 N of push force at the same pressure. For the 230 mm stroke, ensure your mounting arrangement—whether LB foot, FA flange, or TC trunnion—adequately supports the rod to prevent excessive side loading.
Remember that a standard double-acting cylinder will drift if air pressure is lost or the control valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end of stroke and do not function as a braking lock. If your machine requires strict position holding, integrate an external rod lock or a pilot-operated check valve into the pneumatic 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 SGC125X230 FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. 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 force of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, meaning it cannot support CMSG, DMSG, or EMSG switches. You must select the SGC125X230-S variant to enable magnetic sensing capabilities.
