Airtac SGC Standard Cylinder SGC125X150FB
The AirTAC Airtac SGC Standard Cylinder SGC125X150FB is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGC125X150FB
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore actuator uses a genuine ISO 15552 mounting interface to drop directly into existing heavy-duty fixtures. Four steel tie rods clamp the aluminium barrel to the front and rear covers, providing the high rigidity needed for substantial thrust, while a two-way piston seal maintains an internal oil reservoir for long service life. The G1/2 port and M27x2.0 rod thread handle the 30-500 mm/s speed range with adjustable 40 mm air cushions at both ends to smooth out stops.
For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. The default TPU seal handles -20 to +70 C, though a Viton H option extends this to 150 C. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X150FB Is Used
Press Ejection
Provides the robust 6136 N push at 0.5 MPa needed to eject formed metal parts from heavy stamping presses using the FB front flange mount.
Pallet Diversion
Actuates heavy-duty lane diverter arms on packaging lines, utilizing the 150 mm stroke to shift loaded pallets smoothly.
Clamping Fixtures
Secures large workpieces in automated welding cells where the ISO 15552 tie-rod build ensures rigidity under high clamping forces.
Is the Airtac SGC Standard Cylinder SGC125X150FB the Right Cylinder?
When sizing this 125 mm bore option, step down to a smaller ISO 15552 unit if your load requires less than 6000 N, or move up to the 160 mm bore (which provides 10053 N push at 0.5 MPa) for heavier demands. The integrated FB flange mounting simplifies direct face attachment to your machinery. Since this model has no -S magnet, avoid it if your control system requires magnetic end-of-stroke sensors. Remember that the standard air cushion only decelerates the piston near stroke end; it does not function as a brake. If the application must hold a vertical load during air loss or valve centering, install an external rod lock or pilot-operated check valve to prevent drifting.
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 SGC125X150FB FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG or EMSG switches. It uses an ISO 15552 mounting interface with FB flange compatibility, and its tie-rod construction ensures high rigidity for large-bore applications.
