Airtac SGC Standard Cylinder SGC250X500
The AirTAC Airtac SGC Standard Cylinder SGC250X500 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 500mm 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 SGC250X500
Delivering massive thrust for heavy-duty automation, this double-acting tie-rod actuator pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Built to ISO 15552 mounting-interface dimensions, it drops directly into existing large-bore fixtures. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed for such high forces, while a two-way piston seal maintains an internal oil reservoir for long service life.
Because this is a Ø250 bore, TPU seals are not offered; instead, the front-cover packing and buffer gasket use NBR (with a Viton H option available for 0-150 C high-temperature environments). It features a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends. Plan for about 14726 N of real work at 0.5 MPa, which means it lifts roughly 1251 kg vertically with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SGC Standard Cylinder SGC250X500 Is Used
Press Die Ejection
Ejects heavy formed metal panels from large stamping presses using its 24543 N push force at 0.5 MPa.
Pallet Lift Stations
Raises loaded industrial pallets during packaging transitions, safely lifting around 1251 kg vertically with a 2:1 margin.
Injection Mold Clamping
Provides auxiliary clamping pressure on large resin molds, utilizing the 60 mm adjustable cushions to soften end-of-stroke impacts.
Is the Airtac SGC Standard Cylinder SGC250X500 the Right Cylinder?
When sizing this 250 mm bore, verify if the 200 mm bore (15708 N push at 0.5 MPa) might suffice, as the 250 mm is the largest standard SGC option available with no larger size up. For this 500 mm stroke, external guides are strongly recommended to prevent rod bending and manage side loads on the massive piston. Remember that a plain cylinder drifts when air is lost or the valve is centered; the air cushions only decelerate the piston near the stroke ends and do not act as a brake, so install an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 SGC250X500 FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. The air port size is G1, and the rod thread is M42x2.0.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the SGC250X500-S variant for sensor compatibility. The unit is built with a genuine ISO 15552 tie-rod construction for rigid mounting.
