Airtac SGC Standard Cylinder SGC125X350N
The AirTAC Airtac SGC Standard Cylinder SGC125X350N 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 SGC125X350N
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for heavy-duty automation. Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. The NBR seal option makes this variant suitable for specific media resistance needs across its -20 to +70 C operating range.
Equipped with a 350 mm stroke and a G1/2 air port, the 125 mm bore yields a theoretical maximum of 1251 kgf at 1.0 MPa. 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. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X350N Is Used
Press Ejection
Provides the 6136 N push force needed to eject formed metal parts from heavy stamping presses, utilizing the 350 mm stroke to clear the die area completely.
Pallet Dispensing
Separates empty pallets in automated handling lines, where the NBR seals handle varied ambient factory conditions and the robust tie-rod build resists shock loads.
Logistics Diverting
Actuates heavy-duty diverter arms on high-throughput parcel conveyors, moving bulky cartons with reliable double-acting power and adjustable end cushions.
Is the Airtac SGC Standard Cylinder SGC125X350N the Right Cylinder?
When sizing this 125 mm bore, note there is no smaller SGC option below it, while stepping up to the 160 mm bore increases push force to 10053 N at 0.5 MPa. At 350 mm of travel, side-load risks elevate; use external guide rails to prevent rod bending and premature seal wear. This base SKU has no magnet, so if your application requires CMSG or DMSG sensors, select the -S variant instead. Furthermore, an air cushion only decelerates the piston near stroke end—it will not hold a load if air pressure drops. For suspended loads, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 SGC125X350N 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 of 1251 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must purchase the -S variant to use CMSG, DMSG, or EMSG magnetic switches. This model is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore fixtures.
