Airtac SGC Standard Cylinder SGC125X225
The AirTAC Airtac SGC Standard Cylinder SGC125X225 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 225mm 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 SGC125X225
Delivering 6136 N of push force at 0.5 MPa, this double-acting 125 mm bore tie-rod cylinder handles serious industrial loads over its 225 mm stroke. The four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir to maximize service life. Because it adheres to the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom bracketry.
Equipped with a G1/2 air port and a 32 mm hard-chrome piston rod, the unit operates at speeds of 30-500 mm/s. 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. Note that this specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG, or EMSG position switches without changing to a magnetized variant.

Where the Airtac SGC Standard Cylinder SGC125X225 Is Used
Press Die Ejection
Ejects heavy stamped metal parts from press dies using 6136 N of push force over a 225 mm travel distance.
Pallet Stopper Gate
Acts as a robust pneumatic stop gate on heavy-duty roller conveyors, halting loaded pallets weighing up to 313 kg.
Injection Mold Clamping
Provides auxiliary clamping pressure on mid-sized injection molding fixtures where 8590 N at 0.7 MPa is sufficient.
Is the Airtac SGC Standard Cylinder SGC125X225 the Right Cylinder?
When sizing this 125 mm bore unit, verify your actual load requirements against its 6136 N push capacity at 0.5 MPa. If your application demands less force, stepping down is not possible within the SGC family as this is the smallest available bore; you would need to look at smaller standard cylinders. If you need substantially more thrust, the next size up is the 160 mm bore, which provides 10053 N of push force at the same 0.5 MPa pressure. For any stroke length at or beyond 225 mm, ensure your guiding mechanism supports the load to prevent excessive side-loading on the rod. Because this is a double-acting cylinder, it relies entirely on continuous air pressure to maintain position. If air is lost or the valve is centered, the piston will drift. The adjustable 40 mm air cushions only decelerate the piston near the end caps and do not function as a locking brake. To hold a load securely vertically, 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 SGC125X225 FAQ
The SGC125X225 features a G1/2 air port and generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N and the pull force is 8028 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No, this specific SKU does not include the -S magnet option, so it cannot support CMSG, DMSG, or EMSG magnetic switches. To use those sensors, you must select the SGC125X225-S variant. Structurally, the four steel tie rods provide high rigidity, and the ISO 15552 mounting interface allows it to use standard large-bore accessories like FA flanges or LB foot mounts.
