Airtac SGC Standard Cylinder SGC125X600SFA
The AirTAC Airtac SGC Standard Cylinder SGC125X600SFA is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 600mm 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 SGC125X600SFA
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. The G1/2 port and M27x2.0 rod thread handle the required air volume and mechanical linkage.
With a 600 mm stroke, plan for roughly 3682 N of real work at 0.5 MPa, which equates to lifting about 313 kg vertically with a 2:1 safety margin. The included -S piston magnet supports CMSG, DMSG, or EMSG position switches, and the FA flange mount utilizes the standardized ISO 15552 mounting interface for easy fixture integration.

Where the Airtac SGC Standard Cylinder SGC125X600SFA Is Used
Pallet Transfer Diversion
Pushes heavy wood or steel pallets sideways onto secondary conveyor lines using its 6136 N thrust and 600 mm reach.
Vertical Lift Gate Actuation
Raises and lowers loading dock gates or mezzanine safety barriers, safely moving masses up to 313 kg with a 2:1 margin.
Press Tool Ejection
Ejects formed metal parts from large stamping presses, utilizing the front FA flange mount to withstand high impact forces.
Is the Airtac SGC Standard Cylinder SGC125X600SFA the Right Cylinder?
This 125 mm bore sits at the entry point of the SGC large-frame family, offering 6136 N push at 0.5 MPa. If your application requires less force, stepping down is not possible within the SGC range as 125 mm is the smallest available bore; if you need substantially more thrust, the 160 mm bore provides 10053 N at 0.5 MPa. Because this SKU features a 600 mm stroke, external guides are strongly recommended to prevent rod bending and manage side loads during long extensions.
The FA flange accessory provides robust front mounting, but note that a plain pneumatic cylinder cannot hold a load if air pressure is lost or the valve is centered, as the piston will drift. The adjustable air cushions at both ends only decelerate the piston near the stroke limits and do not act as a locking brake. For suspended or vertical loads, 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 SGC125X600SFA FAQ
This 125 mm bore cylinder features a G1/2 air port and generates 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, the FA flange utilizes the ISO 15552 mounting interface, making it dimensionally interchangeable with standard large-bore fixtures. Additionally, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG electronic or reed switches.
