Airtac SGC Standard Cylinder SGC125X30SN
The AirTAC Airtac SGC Standard Cylinder SGC125X30SN is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 30mm 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 SGC125X30SN
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles heavy automation tasks with a compact 30 mm stroke. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the G1/2 port and M27x2.0 rod thread provide robust pneumatic connections. The built-in piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
Equipped with NBR seals, this variant operates reliably across a -20 to +70 C temperature range. The two-way piston seal maintains an internal oil reservoir for extended lifespan. Plan for roughly 3682 N of real work at 0.5 MPa, which means it can safely lift about 313 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC125X30SN Is Used
Short-Stroke Stamping
Ideal for high-force pressing and stamping operations where a 30 mm travel is sufficient to form or seat heavy metal components.
Heavy Pallet Stops
Acts as a rugged stop gate on automated conveyor lines, using its 6136 N thrust to halt fully loaded pallets instantly.
Clamping Fixtures
Secures large workpieces in machining or welding fixtures, providing rigid, high-force clamping that resists vibration.
Is the Airtac SGC Standard Cylinder SGC125X30SN the Right Cylinder?
For short-stroke high-force actuation, this 125 mm bore model provides substantial thrust in a compact footprint. If your application requires less force, there is no smaller bore in the SGC series, so you would need to look at alternative smaller ISO 15552 families. If you need more power, stepping up to the 160 mm bore yields 10053 N of push force at 0.5 MPa. Because this SKU includes the -S magnet, it is fully compatible with CMSG, DMSG, and EMSG sensors.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the adjustable air cushion only decelerates the piston near the end of stroke and does not function as a braking mechanism. To suspend a load safely during an emergency stop or pressure loss, integrate an external pilot-operated check valve or a dedicated rod lock.
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 SGC125X30SN FAQ
This 125 mm bore cylinder features a G1/2 air port and an M27x2.0 rod thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, meaning it drops directly into existing large-bore ISO 15552 fixtures and supports standard LB foot, FA flange, and TC trunnion mounts without modification.
