Airtac SGC Standard Cylinder SGC125X30
The AirTAC Airtac SGC Standard Cylinder SGC125X30 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 SGC125X30
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore cylinder is built for heavy-duty short-travel tasks. As a genuine ISO 15552 tie-rod unit, it drops seamlessly into existing large-bore fixtures via standardized mounting-interface dimensions, simplifying machine upgrades and spares sourcing. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed to handle large-bore thrust without flexing, while a two-way piston seal maintains an internal oil reservoir for long service life.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For real-world sizing, plan for about 3682 N of actual work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The G1/2 port and 30 mm stroke ensure rapid press actions, and the standard TPU seals handle temperatures from -20 to +70 C, with a Viton H option available for environments up to 150 C.

Where the Airtac SGC Standard Cylinder SGC125X30 Is Used
Short-Stroke Stamping
Drives compact stamping and marking presses where a brief 30 mm travel delivers rapid 6136 N impact force.
Pallet Stopper Gate
Acts as a heavy-duty stop block on assembly lines, using its 125 mm bore to halt heavy pallets instantly.
Clamp Actuation
Provides high-force clamping for woodworking or metal fixturing, locking parts securely in 30 mm of travel.
Is the Airtac SGC Standard Cylinder SGC125X30 the Right Cylinder?
When sizing this 30 mm stroke unit, verify if the 6136 N push at 0.5 MPa offers enough headroom; since 125 mm is the smallest SGC bore, stepping up to the 160 mm bore (10053 N push) is your only upgrade path within the series for higher force demands. Keep in mind that a plain double-acting cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end rather than locking it, so add an external rod lock or pilot-operated check valve if the load must be held. For such a short stroke, side-load bending stresses on the 32 mm rod are minimal, but precise rod-end alignment remains critical to prevent premature seal wear.
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 SGC125X30 FAQ
The SGC125X30 generates 6136 N push and 5734 N pull at 0.5 MPa, or 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm rod, and operates at speeds between 30 and 500 mm/s.
Yes, the SGC series is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into the same foot, flange, or trunnion accessories. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic sensors.
