Airtac SGC Standard Cylinder SGC250X300STC
The AirTAC Airtac SGC Standard Cylinder SGC250X300STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGC250X300STC
Delivering massive thrust for heavy industry, the AirTAC SGC250X300STC is a double-acting ISO 15552 tie-rod cylinder built around a 250 mm bore and 300 mm stroke. It generates 24543 N of push force and 23562 N of pull force at 0.5 MPa, scaling up to 34360 N push at 0.7 MPa. Four steel tie rods clamp the aluminum barrel to the covers for extreme rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Because this is a 250 mm bore, the front-cover packing and buffer gasket use NBR rather than TPU, with a Viton H option available for 0-150 C high-temperature environments.
Equipped with a TC trunnion mount and a G1 air port, this unit drops directly into existing ISO 15552 mounting interface fixtures. The -S suffix denotes a built-in piston magnet, enabling CMSG, DMSG or EMSG position switches. 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.

Where the Airtac SGC Standard Cylinder SGC250X300STC Is Used
Heavy Press Stamping
Provides the 24543 N push at 0.5 MPa needed to actuate large forming dies and heavy-duty stamping presses in automotive lines.
Palletizer Actuation
Drives the main lift carriage in automated palletizing cells, safely moving loads up to 1251 kg vertically with a 2:1 safety margin.
Injection Mold Clamping
Secures large injection mold halves using the TC trunnion mount, absorbing high moment loads during the clamping cycle.
Is the Airtac SGC Standard Cylinder SGC250X300STC the Right Cylinder?
Choosing this 250 mm bore is appropriate when you need the maximum standard SGC thrust, as there is no larger bore in the series; stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N. The 300 mm stroke is well within standard limits, but always ensure the TC trunnion mount carries the resulting moment loads without binding. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG or EMSG sensors for end-of-stroke confirmation.
Remember that the adjustable air cushion only decelerates the piston near the end of travel; it does not act as a brake. If the air supply drops or the valve is centered, the piston will drift. To hold a load securely in place during an air loss event, install an external rod lock or a pilot-operated check valve in the system.
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 SGC250X300STC 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.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so standard TC trunnion accessories fit perfectly. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG electronic or reed switches.
