Airtac SGC Standard Cylinder SGC250X410
The AirTAC Airtac SGC Standard Cylinder SGC250X410 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 410mm 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 SGC250X410
Delivering 24543 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles the heaviest pneumatic automation tasks. Four steel tie rods clamp the aluminium barrel to the covers for maximum structural rigidity under extreme thrust, while the two-way piston seal maintains an internal oil reservoir for long service life. For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which lifts roughly 1251 kg vertically with a 2:1 safety margin.
Because this is a Ø250 bore, TPU seals are unavailable; the front-cover packing and buffer gasket use NBR instead, with a Viton H option for 0-150 C high-temperature environments. The unit features a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends. Note that this specific SKU lacks a magnet, meaning it cannot host CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac SGC Standard Cylinder SGC250X410 Is Used
Heavy Press Stamping
Provides the 24543 N push force at 0.5 MPa required to form thick-gauge steel plates in automated metalworking presses.
Pallet Lifter Actuation
Lifts roughly 1251 kg vertically with a 2:1 margin, making it ideal for driving the main carriage in heavy-duty automated palletizing systems.
Injection Mold Clamping
Utilizes its four steel tie rods and 34360 N thrust at 0.7 MPa to hold large industrial molds securely shut during high-pressure resin injection.
Is the Airtac SGC Standard Cylinder SGC250X410 the Right Cylinder?
When sizing this 410 mm stroke actuator, consider the next bore down: the Ø200 SGC delivers 15708 N at 0.5 MPa, which may be insufficient if your load approaches the 1251 kg vertical lift threshold. As the largest bore in the SGC family, the Ø250 stands as the upper limit, so if your application requires more than the 34360 N available at 0.7 MPa, you will need multiple cylinders or a larger format entirely.
Since this 410 mm stroke approaches the longer end of the standard range, ensure external guide rails support the load to prevent rod bending and premature seal wear. Furthermore, a standard double-acting cylinder drifts when air is lost or the valve is centered; the end cushions only decelerate the piston near stroke completion and will not act as a brake. For suspended or vertical loads, install an external rod lock or a pilot-operated check valve.
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 SGC250X410 FAQ
The SGC250X410 delivers 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa. It features a 250 mm bore, 410 mm stroke, G1 air port, M42x2.0 rod thread, 60 mm adjustable air cushions, and operates at 30-500 mm/s.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. Dimensionally, it follows the ISO 15552 mounting interface, allowing it to drop directly into existing large-bore ISO 15552 fixtures and accessory mounts without custom bracketry.
