Airtac SGC Standard Cylinder SGC250X765
The AirTAC Airtac SGC Standard Cylinder SGC250X765 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 765mm stroke, G1 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 SGC250X765
Delivering massive thrust for heavy industrial tasks, this double-acting ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Because the four steel tie rods clamp the aluminum barrel to the covers, the chassis resists deflection under extreme loads, while the two-way piston seal maintains an internal oil reservoir for continuous lubrication. For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin.
This 250 mm bore unit features a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends to absorb end-of-stroke impact. Note that TPU seals are not offered for this bore; the front-cover packing and buffer gasket are NBR, with a Viton H option available for 0-150 C high-temperature environments. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG switches.

Where the Airtac SGC Standard Cylinder SGC250X765 Is Used
Heavy Stamping Press
Provides the 24543 N push force required to actuate large heavy-duty stamping dies and form thick steel plates.
Palletizing Robot
Handles the 1251 kg vertical lift equivalent to lower heavy palletized goods onto conveyor lines with controlled cushioning.
Injection Mold Ejector
Utilizes its 765 mm stroke and NBR seals to slowly push large molded plastic automotive panels out of hot machinery.
Is the Airtac SGC Standard Cylinder SGC250X765 the Right Cylinder?
When sizing this 765 mm stroke actuator, compare it against its neighbors: the 200 mm bore yields 15708 N push at 0.5 MPa, while the 250 mm bore provides 24543 N. If your fixture is already built, the standardized ISO 15552 mounting interface allows direct dimensional interchange with existing large-bore foot, flange, or trunnion accessories. Since the 765 mm stroke is substantial, always use an external guide to prevent rod bending and absorb side loads.
Remember that a standard cylinder will drift if air pressure drops or the valve is centered; the air cushions only decelerate the piston near the end of travel and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. If position feedback is required, switch to the -S magnet variant to enable magnetic sensors.
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 SGC250X765 FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It delivers 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa.
No, because this specific SKU lacks the -S magnet option, it cannot support CMSG, DMSG, or EMSG switches. You must select the -S variant if your application requires magnetic position sensing.
