Airtac SGC Standard Cylinder SGC125X275
The AirTAC Airtac SGC Standard Cylinder SGC125X275 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 275mm 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 SGC125X275
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder uses a robust tie-rod design where four steel rods clamp the aluminum barrel to the covers for high structural rigidity. The standardized ISO 15552 mounting interface ensures it drops seamlessly into existing large-bore fixtures, making it a highly practical choice for spares and new builds alike. A two-way piston seal maintains an internal oil reservoir to maximize service life.
Equipped with a 275 mm stroke and a G1/2 air port, the unit relies on a 32 mm carbon steel rod with a 20-micron hard chrome plating. For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SGC Standard Cylinder SGC125X275 Is Used
Press Die Ejection
Ejects formed sheet metal parts from stamping presses using the 275 mm stroke to clear the die area completely before the next cycle.
Pallet Squaring Station
Applies lateral push force to align pallets or heavy tote bins on a conveyor line prior to stretch wrapping or automated stacking.
Diversion Gate Actuator
Drives heavy-duty mechanical diversion gates on high-speed parcel sorting conveyors, utilizing the 6136 N thrust to overcome gate inertia.
Is the Airtac SGC Standard Cylinder SGC125X275 the Right Cylinder?
When sizing this actuator, consider the adjacent bores in the SGC range: the larger 160 mm bore provides 10053 N of push at 0.5 MPa for heavier demands, while there is no smaller standard SGC bore below 125 mm. Because this 275 mm stroke is relatively long, ensure external guide rails are used to prevent rod bending and absorb any side-load forces during extension. Furthermore, a standard double-acting cylinder will drift if air pressure is lost or the valve is centered; the adjustable air cushion only decelerates the piston near the end of travel and does not function as a locking brake. To safely suspend a load, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SGC125X275 FAQ
This 125 mm bore cylinder 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 increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot accommodate CMSG, DMSG, or EMSG magnetic switches. However, its ISO 15552 mounting interface allows full interchangeability with standard large-bore fixtures, and the tie-rod construction ensures high rigidity under heavy thrust loads.
