Airtac SGC Standard Cylinder SGC125X100FA
The AirTAC Airtac SGC Standard Cylinder SGC125X100FA is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGC125X100FA
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore cylinder handles heavy automation tasks. The four steel tie rods clamp the aluminum barrel to the covers, providing high rigidity under large-bore thrust, while the two-way piston seal maintains an internal oil reservoir for long service life. It features a G1/2 air port and an M27x2.0 rod thread.
Because it follows the ISO 15552 mounting interface, this FA flange-mounted unit drops directly into existing large-bore fixtures. For practical sizing, 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 the -S magnet, so it cannot host CMSG, DMSG or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X100FA Is Used
Press Fit Assembly
Drives bearings into heavy housings on automotive production lines using its 6136 N thrust at 0.5 MPa.
Pallet Diverting
Extends 100 mm to push loaded pallets onto secondary packaging lanes via the rigid FA flange mount.
Gate Actuation
Opens and closes heavy bulk-material chute gates in logistics hubs, relying on the tie-rod build for structural stability.
Is the Airtac SGC Standard Cylinder SGC125X100FA the Right Cylinder?
When sizing this 125 mm bore option, verify if the 6136 N push at 0.5 MPa provides adequate thrust; moving up to the 160 mm bore yields 10053 N, while 125 mm is the smallest available SGC size. The included FA front flange makes it straightforward to mount rigidly to machine frames. Since this SKU has no -S suffix, you must choose an -S variant if your application requires CMSG, DMSG or EMSG magnetic sensing. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the adjustable air cushion only decelerates the piston near the stroke ends and will not hold a suspended load. For vertical safety, 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 SGC125X100FA FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet and cannot host CMSG, DMSG or EMSG switches. You must select the -S variant for position sensing. It uses an ISO 15552 mounting interface for fixture interchangeability.
