Airtac SGC Standard Cylinder SGC250X225S
The AirTAC Airtac SGC Standard Cylinder SGC250X225S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 225mm 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 SGC250X225S
Delivering massive thrust, this double-acting AirTAC SGC250X225S large-bore cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for extreme structural rigidity under heavy loads, while a two-way piston seal maintains an internal oil reservoir for long operational life. Because this is a Ø250 bore, the front-cover packing and buffer gasket utilize NBR rather than TPU, with a Viton H option available for 0-150 C high-temperature environments.
It features a G1 air port, an M42x2.0 rod-end thread, and a 60 mm adjustable air cushion at both ends to decelerate the payload smoothly. The built-in -S piston magnet enables direct mounting of CMSG, DMSG, or EMSG switches for position sensing. Plan for roughly 14726 N of real work at 0.5 MPa, which safely lifts about 1251 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC250X225S Is Used
Heavy Stamp Pressing
Drives large tonnage forming and stamping dies in automotive lines, utilizing the 24543 N push force to shape thick steel plates reliably.
Pallet Lift Stations
Actuates robust lifting platforms in high-capacity warehouse docks, easily hoisting loaded pallets weighing up to 1251 kg vertically.
Injection Mold Clamping
Secures heavy industrial molds in large plastic injection machinery, relying on the rigid four tie-rod construction to resist deflection.
Is the Airtac SGC Standard Cylinder SGC250X225S the Right Cylinder?
When sizing this 225 mm stroke unit, consider the stepping logic across the SGC family: the Ø200 bore provides 15708 N of push force at 0.5 MPa, while the Ø250 shown here outputs 24543 N, representing the maximum thrust tier available in this series. For any application exceeding 500 mm of stroke, incorporating external guide rails is critical to prevent rod bending and premature seal wear from side loads.
This SKU includes the -S magnet for CMSG/DMSG/EMSG sensors, but remember that a standard SGC cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The end cushions only decelerate motion near stroke end, so integrate an external rod lock or pilot-operated check valve if your fixture requires suspended load holding.
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 SGC250X225S FAQ
This Ø250 bore model 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 force of 5006 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into matching large-bore fixtures. The included -S magnet allows CMSG, DMSG, and EMSG switches to be fitted for position detection.
