Airtac SGC Standard Cylinder SGC125X400SN
The AirTAC Airtac SGC Standard Cylinder SGC125X400SN is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 400mm 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 SGC125X400SN
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-bore automation tasks. The 125 mm bore utilizes a G1/2 air port and an M27x2.0 rod thread, while four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG position switches.
For practical sizing, 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 -N designation specifies NBR seals for this unit, and the adjustable air cushions at both ends provide smooth deceleration over the 400 mm travel.

Where the Airtac SGC Standard Cylinder SGC125X400SN Is Used
Press Ejection
Provides the 6136 N push force needed to eject formed metal parts from a hydraulic press bed over a 400 mm travel distance.
Pallet Stops
Acts as a heavy-duty pneumatic stop for 313 kg loaded pallets on a conveyor, using the NBR seals for general industrial durability.
Material Lifts
Raises heavy tooling fixtures in an assembly cell, relying on the CMSG sensor feedback to confirm the 400 mm extension.
Is the Airtac SGC Standard Cylinder SGC125X400SN the Right Cylinder?
When sizing this 125 mm bore option, stepping down is not possible within the SGC family as it is the smallest available size. If your application requires more power, the next larger 160 mm bore provides 10053 N of push force at 0.5 MPa compared to this model's 6136 N. To hold a load vertically or prevent drift on air loss, add an external rod lock or pilot-operated check valve, since the air cushion only decelerates the piston near stroke end without locking it. With a 400 mm stroke, ensure adequate guiding to prevent rod bending under side loads.
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 SGC125X400SN 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.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard LB foot, FA flange, or TC trunnion fixtures alongside its rigid tie-rod construction.
