Airtac SGC Standard Cylinder SGC125X50SFA
The AirTAC Airtac SGC Standard Cylinder SGC125X50SFA is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 50mm 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 SGC125X50SFA
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminum barrel to the covers, providing the rigidity needed to handle large-bore thrust without flexing. The two-way piston seal maintains an internal oil reservoir for extended operational life.
Because of the built-in magnet (-S), you can track piston position directly with CMSG, DMSG, or EMSG 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 G1/2 port and M27x2.0 rod thread are fixed by the 125 mm bore, and the standard FA flange mount simplifies bolting to your fixture.

Where the Airtac SGC Standard Cylinder SGC125X50SFA Is Used
Press Fit Assembly
Drives bearings into heavy housings using the 6136 N push force, with the 50 mm stroke providing a fast, controlled insertion cycle.
Pallet Ejection
Pushes loaded pallets off a roller line using the FA flange mount, safely moving parts weighing up to 313 kg vertically.
Heavy Clamping
Secures large metal fabrications during welding, utilizing the ISO 15552 interface to swap easily into existing tooling grids.
Is the Airtac SGC Standard Cylinder SGC125X50SFA the Right Cylinder?
When sizing this 125 mm bore model, compare it against its siblings: stepping down is not an option within the SGC range, while stepping up to the 160 mm bore yields 10053 N of push force at 0.5 MPa. Choose this 50 mm stroke version for short, powerful clamping or ejecting motions where a longer extension would waste cycle time.
The FA flange accessory bolts securely to the front cover for rigid mounting. Remember that a standard cylinder drifts when air is lost or the valve centers, as the air cushions only decelerate the piston near stroke end rather than locking it. For suspended loads that must hold position, add an external rod lock or 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 SGC125X50SFA FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, and 8590 N push / 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The body uses the ISO 15552 mounting interface, so the FA flange and other standard accessories drop right in.
