Airtac SGC Standard Cylinder SGC125X350
The AirTAC Airtac SGC Standard Cylinder SGC125X350 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGC125X350
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore, 350 mm stroke actuator is built for heavy-duty automation. The SGC125X350 is a double-acting ISO 15552 tie-rod cylinder, using four steel rods to clamp the aluminium barrel to its covers for high structural rigidity. Because it follows the standard ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without redesigning brackets. The two-way piston seal retains an oil reservoir for continuous lubrication and long service life.
At 0.5 MPa, plan for about 3682 N of real work, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG switches; add the -S variant if you require position sensing. The bore dictates a G1/2 port and an M27x2.0 rod thread, while adjustable 40 mm air cushions at both ends absorb end-of-stroke impact. Standard TPU seals handle temperatures from -20 to +70 C, with Viton H available for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC125X350 Is Used
Pallet Diversion Gate
Actuates heavy lane diverters on packaging lines, using its 6136 N thrust to push fully loaded pallets smoothly across transfer sections.
Vacuum Forming Press
Provides the steady clamping pressure required to hold plastic sheets against mold frames, utilizing the 350 mm stroke for deep-draw operations.
Scissor Lift Actuation
Drives the extension arms on material handling lifts, moving approximately 313 kg of vertical load with a safe 2:1 margin at 0.5 MPa.
Is the Airtac SGC Standard Cylinder SGC125X350 the Right Cylinder?
When sizing this 125 mm bore model, verify your actual load against its 6136 N push and 5734 N pull ratings at 0.5 MPa. As the smallest bore in the SGC family, there is no smaller standard option; if your application requires less force, you would step outside the SGC line, whereas heavier demands move up to the 160 mm bore (10053 N push at 0.5 MPa). Remember that a standard double-acting cylinder drifts when air is lost or a valve centers—the 40 mm cushions only decelerate the piston near stroke end and do not act as a brake. For suspended or vertical loads, install an external rod lock or pilot-operated check valve.
With a 350 mm stroke, you must account for side-load risks and rod bending. Ensure your mounting arrangement—whether LB foot, FA flange, or TC trunnion—provides rigid guidance to prevent rod deflection. Since this base configuration has no magnet, it cannot support magnetic sensing; choose the SGC125X350-S if your control system requires CMSG, DMSG, or EMSG switches.
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 SGC125X350 FAQ
The SGC125X350 delivers 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 of 1251 kgf at 1.0 MPa. It features a G1/2 air port, an M27x2.0 rod thread, and operates at speeds of 30-500 mm/s.
No, this specific SKU does not include a magnet. You must select the SGC125X350-S variant to use CMSG, DMSG, or EMSG magnetic switches. Additionally, its ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures, and the tie-rod build provides high rigidity.
